The following plots are accompanied by their Pearson product-moment correlation coefficients image credit :.

But notice that the horizontal line has an undefined correlation. We just don't know! Intuitively, there's no way we can regresskon the correlation from the available data. So we have zero on the denominator. Unsurprisingly, this will not be defined either. In this answer I have only considered the case of simple linear regression, where the response depends on one explanatory variable.

But the argument also applies to multiple regression, where there are several explanatory variables. The response you describe fails what is a good elementary school meet at least criterion 5, so the General Linear Model does not apply to this example. Sign up to join this community.

Model residuals are conditionally independent.

Model residuals are distributed with conditional mean zero. Model residuals have constant conditional variance. Model residuals are conditionally esuation in distribution. Equaton theorem still applies even if residuals aren't normal, for instance, though lack of normality can have other impacts on interpretation of results t tests, confidence intervals etc. This is an extreme example of the fact that data recorded to a finite accuracy can't have strictly normal errors.

How would you tackle it then? In fact, I don't think 5 ever applies to real data! Sure, regression can be performed with all kinds of residual distributions, and 5 is not related to the calculation of RSS. As Silverfish says, 5 relates to the evaluation and interpretation of estimated quantities simple linear regression equation explained p-values and confidence limits, quantities that render the General Linear Model useful for inference and not merely sipmle.

If the calculated value of F exceeds the critical value, then the original hypothesis must be rejected and the regression model is proved to be significant, which proves that all explanatory variables connected together have a direct impact on Y.

Abstract In industrial economy, the main factors influencing the urban construction and development of social economy is linked to the high-speed rail site accessibility, and this has its influence on the regional economy as a whole, and as an example, this can be explained through the study using a multiple linear regression equation model, built and compared before and after 2 years of data and tegression.
