Linear Regression Using Solver Linear regression creates a statistical model that can be used to predict the value of a dependent variable based on the value(s) of one more independent variables. The example dataset below was taken from the well-known B
example below, the name "Linear price-demand model" was used. If the regression procedure is re-run while positioned on a previous model's output worksheet, the specifications of that model are the starting point for the next one, allowing models to be elaborated and refined in a systematic...
