What is regression testing in English?
Regression testing (rarely, non-regression testing) is re-running functional and non-functional tests to ensure that previously developed and tested software still performs as expected after a change. If not, that would be called a regression.
What package is lm in R?

What library is bptest in R?
Example: Breusch-Pagan Test in R In this example we will fit a regression model using the built-in R dataset mtcars and then perform a Breusch-Pagan Test using the bptest function from the lmtest library to determine if heteroscedasticity is present.
What does LM() do in R?
The lm() function creates a linear regression model in R. This function takes an R formula Y ~ X where Y is the outcome variable and X is the predictor variable. To create a multiple linear regression model in R, add additional predictor variables using + .
