Dear all
I want to run a simple multiple linear regression model, say:
mod <- lm(y~x1+x2+x3+x4)
I have programmed a custom algorithm to calculate the p-values, because
there is clustering present.
I ordered the variables according to their p-value and want to stepwise
eliminate the variables with the highest p-values.
My question: How can I use "update" when I have only the variable name als
string (e.g., "x1")? Or is there another convenient way to update the
model?
Thanks!
Sincerely,
Denis
