  • 1.  How to perform Multiple Regression by splitting data into Train and test

    Posted Tue February 28, 2023 01:03 AM

    I am looking to do split my data into 80% train and 20% test arbitrarily such that I will know later which it chose for train which for test and did the validation

    which good charts.

    The regression on train should be best subsets with a maximum of 3 to 4 variables only 

    once train is done it should run on the test and validate the performance

    I would except a good R^2 and adjusted R^2 and a significant model

    Need help 

    Anyway to directly do this
