WebNow, we apply regsubsets() to the training set in order to perform best subset selection*. ( *Note: If you're trying to complete this lab on a machine that can't handle calculating the best subset, or if you just want it to run a little faster, try forward or backward selection instead by adding the method = "forward" or method = "backward" parameter to your call to … Web10 okt. 2024 · Hello @Hiteshsingal, your problem is (or at least starts with) data fields (columns) with spaces in the field name. Try to avoid this. However if you need to use such a data.frame use backquotes (`) to indicate the fields you need.
