Other JavaScript in this series are categorized under different areas of applications in the MENU section on this page. Professor Hossein Arsham Regression models are often constructed based on certain conditions that must be verified for the model to fit the data well, and to be able to predict accurately. This site provides the necessary diagnostic tools for the verification process and taking the right remedies such as data transformation.

Prior what does linear regression mean in stats using this What does linear regression mean in stats it is necessary to construct the scatter-diagram of your data. If by visual inspection of the scatter-diagram, you cannot reject "linearity condition", what does linear regression mean in stats you may use this JavaScript. Enter your up-to sample paired-data sets X, Yand then click the Calculate button. Blank boxes are not included in the calculations but zeros are.

In order to perform serial-residual analysis you must enter the independent variable X in increasing order. Match the cause and effect in the box below In entering your data to move from cell to cell in the data-matrix use the Tab key not arrow or enter keys.

Predictions by Regression: Confidence interval provides a useful way of assessing the quality of prediction. In prediction by regression often one or more of the following constructions are of interest: A confidence interval for a single future value of Y corresponding to a chosen value of X. A confidence interval for a single pint on the line.

A confidence region for the line as a whole. Confidence Interval Estimate for a Future Value: A confidence interval of interest can be used to evaluate the accuracy of a single future value of y corresponding to a chosen value of X say, X 0. This JavaScript provides confidence interval for an estimated value Y corresponding to X 0 with a desirable confidence level 1 - a. Confidence Interval Estimate for a Single Point on the Line: If a particular value of the predictor variable say, X 0 is of special importance, a confidence interval on the value of the criterion variable i.

This JavaScript provides confidence interval on the estimated value of Y corresponding to X 0 with a desirable confidence level 1 - a. It is of interest to compare the above two different kinds of confidence what does linear regression mean in stats. The first kind has larger confidence interval that reflects the less accuracy resulting from the estimation of a what does linear regression mean in stats future value of y rather than the mean value computed for the second kind confidence interval.

The second kind of confidence interval can also be used to identify any outliers in the data. Confidence Region the Regression Line as the Whole: When the entire line is of interest, a confidence region permits one to simultaneously make confidence statements about estimates of Y for a number of values of the predictor variable X. In order that region adequately covers the range of interest of the predictor variable X; usually, data size must be more than 10 pairs of observations.

In all cases the JavaScript provides the results for the nominal data. For other values of X one may use computational methods directly, graphical method, or using linear interpolations to obtain approximated results. These approximation are in the example of strengths based approach in social work directions i.

Este sitio proporciona las herramientas diagnosticas necesarias para el proceso de verificación y correcta selección de remedios tales como la transformación de datos. Antes de utilizar este JavaScript es necesario construir un diagrama de dispersión para sus datos. Introduzca hasta 84 pares de datos X, Yy luego presione el botón Calculate Calcular. Mientras entre sus datos en la matriz, muévase de celda a celda usando la tecla Tab, no use la flecha o la tecla de entrada.

Un intervalo de confianza para un solo punto sobre la línea. Una región de confianza para la línea como una totalidad. Estimación de Intervalos de Confianza para un Valor Futuro: Un intervalo de confianza de interés puede ser utilizado para evaluar la precisión de un valor futuro simple de Y correspondiente a un valor dado X como X0.

Estimación de un Intervalo de Confianza para un Solo Punto sobre la Línea: Si un valor en particular de la variable de predicción digamos, X0 tiene una importancia especial, un intervalo de confianza sobre el valor de la variable de criterio por ejemplo, el average de Y a X0 correspondiendo a X0 podría ser nuestro objetivo. Es interesante el comparar las diferencias entre las aplicaciones de los tipos de intervalos de confianza diferentes explicados anteriormente. Con el objetivo de cubrir adecuadamente el rango de interés de la variable de predicción X; usualmente, el tamaño de los datos debería ser de por lo menos 10 observaciones.

En todos los casos el JavaScript proporciona los resultados para los datos nominales. What decreases risk of colon cancer otros valores de X se podrían utilizar directamente métodos computacionales o interpolaciones lineales para obtener resultados aproximados. Professor Hossein Arsham.
