In order to deal with both overdispersion and excess of zeros, a ZINB regression model is highly recommended Hilbe,and this holds in particular for analysing civil conflicts as they are rare events but, at bteween same time, the roots of in stability can be manifold Bagozzi, Accordingly, they how to find non linear relationship between two variables be interpreted as cell-based fixed effects proxying omitted variables specifically related to territorial features. Climate change, weather shocks, and violent conflict: A critical look at the evidence. The regression coefficient is positive, showing a positive correlation with the stock price V. The DW statistic is 0. It is also interesting relationsihp compare the results obtained under the inflated model with those of a linear normal model, shown in last betwesn columns of Table A1. Ide, T. Article Google Scholar Lee, L.

The article uses SPSS statistical analysis software to establish a multiple linear regression model of short-term stock price changes of domestic agricultural listed companies. The article uses a stable time series based on the ARMA model for stable agricultural value-added, fiscal expenditure and market interest rates. The regression method is used to study its impact on the stock price index. Compared with the existing stock forecasting methods, this method has simple data collection and no specific requirements for data selection, and the prediction results have a high degree of fit.

Therefore, this method is suitable for most stocks. Related agricultural products are listed on the market [ 1 ]. As a result, the company has also become the focus of attention. Therefore, studying what is emergency services in hospital financial performance of agricultural-related listed companies helps public investors understand the development status of agricultural listed companies and can also provide a particular reference for the government to formulate relevant policies.

Some scholars analysed the company's financial performance that completed the share-trading reform, what is molecularity of a relation explain its types by examples the entropy method to explore its correlation and concluded that the correlation between financial performance and stock price is very weak.

Some scholars have chosen multiple linear regression methods to discuss and analyse the impact of company performance and stock prices [ 2 ]. They concluded that the most influential is the profitability and development ability of listed companies in agricultural products processing. Some scholars have used panel data models to analyse the relationship between company stock prices and profit levels to prove a significant correlation between the two.

The CCR model verifies the correlation between financial indexes and stocks and evaluates the stock selection in the portfolio based on how to find non linear relationship between two variables correlation. Finally, they analysed whether the monetary policy issued by the country has a particular impact on the company's stock price. They obtained the conclusion that the impact of monetary policy on the stock price varies according to regional differences [ 3 ].

They used a variety of methods to examine the impact of financial performance on stock prices. They found that EPS, book value, dividend coverage, growth rates, and dividend yields positively correlate with stock prices. In contrast, dividends per share and price-earnings ratios are negatively correlated with stock prices. There are relatively few studies on the impact of financial indicators on stock prices of agricultural listed companies.

How to find non linear relationship between two variables selection of financial indicators is not comprehensive enough, and the analysis method is mainly based on multiple statistical regression. Because of this, this article analyses from the four perspectives of profitability, growth ability, operating ability and solvency [ 4 ]. We select appropriate financial information indicators and apply the econometric panel data model to analyse the relevance of stock prices of listed agricultural companies in China to financial performance.

We use the above methods to study the impact of the financial performance of Chinese agricultural listed companies on stock meaning of scatter in english and urdu. The data in this article comes from the Sina Finance Market Center. After how to find non linear relationship between two variables companies with insufficient financial data, we selected 8 financial indicators of 14 listed agricultural companies from to as sample data.

This article selects a total of 8 financial indicators from 4 aspects of profitability, growth ability, operating ability and solvency: EPS X 1central business profit margin X 2primary business income growth rate X 3net asset growth rate X 4Total asset turnover rate X 5current asset turnover rate X 6quick ratio X 7 and interest payment multiple X 8. Profitability refers to the company's ability to make effect meaning in telugu under normal operating conditions.

In today's market, the competition between industries and products is becoming increasingly fierce, and the stock market is volatile [ 5 ]. Therefore, analysing the company's profitability is of great significance to the company's sustainable development and operation. In addition, how to find non linear relationship between two variables can provide a reference for stakeholders to make financial decisions and play a key role in predicting future cash flows. Among the various indicators for analysing profitability, EPS and paramount business profitability have been widely used as core indicators.

EPS X 1. EPS is the company's net profit per share for 1 year. EPS equal the company's total profit after tax divided by the company's total equity. EPS is one of the indicators reflecting the company's operating results. It is the critical basis for stakeholders to evaluate profitability, and it is also the most critical indicator of the company's profitability. The profit margin of the leading business indicates the ratio of the profit earned by the company's main activities to its net income over some time.

This indicator how to find non linear relationship between two variables a significant role in evaluating the company's profitability. Growth ability refers to the development trend of the company at this stage and in the future. Whether it can expand its scale and increase profits can reflect the company's development prospects. The company's growth capability analysis can judge the company's future cash flow changes in operating activities and better analyse the company's future financial fluctuations [ 6 ].

Primary business income growth rate X 3. The main business income growth rate is the income earned by the company's main activities during this period minus the income earned by the company's main activities during the previous period and then divided by the company's main activities during the above period arrive at the ratio of income. The growth rate of net assets represents the ratio of the company's high net assets during the current period to the total net assets in the previous period.

This indicator is used to indicate the growth progress of the company's capital scale and measure the company's ability to grow [ 7 ]. Operational capacity refers to the company's ability to use its assets to obtain benefits. Functional ability plays a decisive role in the company's solvency and profitability, and it is the core content of financial analysis.

Operating ability is mainly manifested in the turnover rate of what makes a negative correlation assets. Among various asset turnover rates, total asset turnover and current asset turnover are the leading indicators. As a result, they can better reflect the company's operational capabilities.

The turnover rate of total assets X 5 [ 8 ]. This indicator is very critical for evaluating the company's operational capabilities. The turnover rate of current assets refers to the net income ratio of the company's production and operation to the total average current assets during the period [ 9 ]. This indicator plays a significant role in evaluating the company's operational capabilities.

Solvency refers to the ability of the company to repay the debts it borrows from the outside world when it reaches the time of return. Is it possible to repay the due debts promptly [ 10 ]? The former is the primary indicator to measure short-term debt solvency, and the latter is the primary indicator to measure long-term debt solvency. Quick ratio X 7. When explaining the solvency of a company or enterprise in a short period, it can be analyszed by comparing the quick ratio.

The interest payment multiple is also called the interest earned multiple. It is the primary basis for measuring the company's long-term debt repayment ability. It also refers to the company's ability to use operating profits to repay debt and interest. What is recorded in the matrix is a particular data index of X objects at Y time nodes.

In recent decades, a variety of statistical methods have emerged, including panel data analysis methods. Panel data is generally analysed by Eviews software, so this paper selects Eviews6. Y it is the dependent variable, which represents the stock price of a company i in year t. We use it to explain personal effects. That is to say. It is used to explain the effects of variables that are neglected to explain individual differences in the model.

X it is the independent variable, where i represents the company and t represents the time. We use Eq. We must analyse whether there are unit roots in a sequence we choose. Once we find that there is a unit root, we call this series a non-stationary time series. Such a sequence will lead to spurious regression when performing regression analysis [ 11 ]. Therefore, to ensure the data's how to find non linear relationship between two variables, we must first perform a unit root test on the selected sequence.

First, we use the obtained P-value to indicate whether the data contain unit roots. Otherwise, it is considered that the data has a unit root, and the data is not stable. As can be seen from Table 1the P-value obtained by LLC inspection of the stock prices of 14 agricultural listed companies and eight financial index data from to is 0. The P values are all 0. The research results show that the data in this paper do not contain unit roots. Therefore, the data in this article are all stable, and we can conduct an empirical analysis on them.

According to the characteristics of this article, we select the variable intercept model as the evaluation method. The Hausman test method is usually used to select a specific model [ 12 ]. Assume no correlation between the individual influence and the independent variable in the random influence model. The first step is to do a regression analysis of the original data. Then, we selected and used the random influence variable intercept model on the model, and the estimated results are shown in Table 2.

In the second step, Hausman's test how to find non linear relationship between two variables is used to determine whether the conclusion obtained by the random influence model analysis is appropriate. The results obtained by this method are shown in Table 3. What are the disadvantages of quasi experimental design can be seen from Table 3 that the model statistic is Therefore, a fixed-effect variable-intercept model should be established.

The calculated results of the model are shown in Table 4. The results show that the accuracy of this model is high, and the explanation is robust. The corresponding P-value is 0. The explanatory variables selected eight indicators explain the stock price is feasible. Therefore, the data of the eight indicators we selected from the four aspects of profitability, growth ability, operating ability and solvency are reliable.

The coefficient of determination R2 in the process of the fitness test is 0. This result is still relatively ideal in the time series model. The reason may be that the company's finances are sometimes affected by some uncertain factors, causing the current stock price to fluctuate. However, from the perspective of the degree of fit, these fluctuations have little effect on the test index data, and they can be effectively analysed and studied.

Journal of Peace Research, 4935— The Stata Journal, 13 4— Political Geography, 4351— Journal of Peace Research, 4951— This empirical framework better accounts for the propensity of violence in small areas even if they have not experienced any conflicts in the past. First, the African continent has historically faced a larger number of droughts with respect to floods, resulting in a higher geographical and temporal coverage number of cells and years in our panel of drought events which may force parts of the population that rely directly on agriculture for subsistence to migrate to more favourable places, thus altering the social equilibria in the destination places.
