Regression testing is an iterative process executed throughout the software development and testing cycle. Regression testing focuses on previously tested aspects, features which were tested and found working, or bugs which were found and confirmed fixed, in earlier versions of the software. The purpose of regression testing is to make sure that those previously verified features still work.
For example, consider a software release that includes two new features, A and B. While the developers are still working on feature B, test is already examining feature A. When A is found working as planned, testing proceeds to feature B, while regression testing affirms that nothing in feature B broke A.

regression testing is a white box testng
regression testing is normally a set of automated scripts written by the test/automation team to test all previously existing functionality to make sure nothing has been broken.
Just like that

To complete testing application if any modification done any modules or functionality that is called regression testing.
fixed
Regression are classified as - Full / Complete Regression -- Entire application is regressed - Regional regression -- Tests performed around defect fixes or code changes
system testing is a kind of retesting where we can test whole system after integration. while regression testing is a process where we do the rerunning the test cases and check whether that re run doesnot affects the real environment.
This question needs to be more specific. Are you asking for an example of statistical regression?
Regression testing is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes such as enhancements, patches or configuration changes, have been made to them.
