Not what you're looking for?

Ask Custom Question

How might you go about creating a stronger regression model? For example, you have a multiple regression model with an adjusted R-Square of 0.49, which would explain 49% of the variance of the dependent measure, and you would like to explain 70% of the variance of the dependent measure.

Solution Summary

In the solution, 2 methods of improving model fit are considering. Procedures are given for the 2 methods.

Solution Preview

There are two ways to improve model fit (r-square and/or adjusted r-square).

(1) Remove independent variable(s) that are not strongly correlated with the dependent variable. A good procedure to use would be something like this....

Remove the least significant independent variable from the regression model. This would be the variable with the lowest ...
