r - Regarding multiple linear models simultaneously

Question

I am trying to run many linear regressions models simultaneously. Please help me to make a code for this.

I am working on two data frames. In first data frame have 100 dependent variables and in second data frame i have 100 independent variables. Now I want simple linear models like

lm1 <- lm(data_frame_1[[1]] ~ data_frame_2[[1]])
lm2 <- lm(data_frame[[2]] ~ data_frame[[2]]) 

and so on .That means I have to run 100 regression models. I want to do this simultaneously. Please help me to make respective codes to run these all models simultaneously.

Answer 1

It is not that clear what you mean by simultaneously. But maybe doing a loop is fine in your case?

model.list = list()
for (i in 1:100){
  model.list[[i]] = lm(data.frame.1[[i]] ~ data.frame2[[i]])
}
