What is a measure of the explanatory power of the regression model?
Regression analysis describes the relationship between two or more variables. The measure of the explanatory power of the regression model is R2 (i.e. coefficient of determination).
What is p value in regression analysis?
The p value is NOT a probability but a likelihood. It tells you the likelihood that the coefficient of a variable in regression is non zero. The p-value is: The probability of observing the calculated value of the test statistic if the null hypothesis is true
How do you do regression testing and can we give one example on that in the same application?
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.
What is the purpose of regression testing in software development?
Regression is the re-test of the existing features of your softwares. Criterias: -If one of the requirements is enhanced or changed or modified then the affected other software modules should also be tested as regression test. -If the already released software modules are having issues at end customer side and they have reported bugs in them...Then you will come to know the most affected module and can perform regression test in next release.
What does one have to do before a regression analysis?

What is the role of the stochastic error term in regression analysis?
Regression analysis is based on the assumption that the dependent variable is distributed according some function of the independent variables together with independent identically distributed random errors. If the error terms were not stochastic then some of the properties of the regression analysis are not valid.
What is heteroscadacity?
In regression analysis , heteroscedasticity means a situation in which the variance of the dependent variable varies across the data. Heteroscedasticity complicates analysis because many methods in regression analysis are based on an assumption of equal variance.
