How to write a loop in R to select multiple regression model and validate it ?
...ets I would like to run the following code:
library(leaps)
forward <- regsubsets(Y ~.,data = training, method = "forward", nbest=1)
backward <- regsubsets(Y ~.,data = training, method = "backward", nbest=1)
stepwise <- regsubsets(Y ~., data = training, method = "seqrep", nbest=1)
exhaustive <- regsubsets(Y ~.,data = training, method = "forward", nbest=1)
summary(forward)
summary(backward)
summary(stepwise)
summary(exhaustive)
I would like R programme to select the best model (with the highest adjusted
R2) using each of the selection methods, so...
