Hi, all recently working on linear regression model , i like it too much but there was one doubt what are the limitation of this model and if there is limitation then how to identify by seeing the stats parameter like t or p value or coefficient .
well i am very bad in story mode and too lazy person so i would like to proceed in points mode
> if identifying linear regression model validation limitaion then tell me on following perspective:

R studio > is there any command argument to check linear regression before applying on data set
statsistics mean is there any parameter to check like t value, p value anything
