At a high level, regression tests are tests that you have for things that currently work in the product, and should continue to work the same way in the future The F-test of overall significance indicates whether your regression model provides a better fit than a model that contains no independent variables

I read a lot of studies in my graduate school studies, and it seems like half.. Regression testing is done when: Any patches added to software or configuration of software has been changed. If new Change Requests are implemented to the build F-test. When the regression is conducted, an F-value, and significance level of that F-value, is computed. If the F-value is statistically significant (typically p < .05)..
