Multiple regression analysis is used when one is interested in predicting a continuous dependent variable from a number of independent variables. J. Lets see how to do this step-wise. Additional terms will always improve the model whether the new term adds significant value to the model or not. But then you’d end up with a very large, complex model that’s full of terms which aren’t actually relevant to the case you’re predicting. While running this analysis, the main purpose of the researcher is to find out the relationship between the dependent variable and the independent variables.
