Question

Quizplus · Accepted Answer

Stepwise regression is a process where a computer program automatically selects which independent variables should be added or removed from a regression model based on statistical significance. This method can help to avoid the problem of overfitting and improve the accuracy of the model. Nonlinear regression, linear regression, residual analysis, and sensitivity analysis are not specifically related to the process of systematically adding or deleting variables from a regression model.
