The dummy variable allows each firm type to have a different intercept and slope. The previous model can be broken down into a model for each firm type by plugging in the values for X2 i. If X2 i =0, ...

The Linear Stats Project is a Go program designed to read data from a file and compute two key statistical metrics: Linear Regression Line: Computes the best-fit line for the given data points.

3. Calculate a regression equation, using the scores on the first course as the independent variable and the scores on the second course as the dependent variable. First the slope: Then the intercept: ...

This applet allows you to remove individual observations and note the effect on the slope and intercept of the regression line. This is illustrated in the following display, using the data on Alcohol ...

As a widely used technique in statistics, the regression line helps quantify the relationship between dependent and independent variables. This powerful method aids researchers and analysts in ...
