All combinations possible in a mutliple regression
Hi,
I want to use four independent variables to predict the output of one
dependent variable using a linear model lm. I want to compare all possible
combinations of the 4 independent variables, including singles, pairs and
triples.
I was thinking of using the AIC test to compare all models and pick the best
one.
The model looks like this :
lm(Y ~ X1 + X2 + X3 + X4)
Thanks for your help
