Suppose I have the following data:
y<-rnorm(10)
age<-rnorm(10)
sex<-rbinom(10,1, 0.5)
edu<-round(runif(10, 1, 20))
edu2<-edu^2
df<-data.frame(y,age,sex,edu,edu2)
I want to run a large number of models, for example:
lm(y~age)
lm(y~age+sex)
lm(y~age+sex+edu)
lm(y~age+sex+edu+edu2)
lm(y~sex+edu2)
lm(y~age+edu+edu2)
....
But I would like to first define a list containing all possible sets of
regressors, and then execute each one in a loop/lapply. Unfortunately I
got lost in trying to paste variables' name in the formula with no result.
many thanks in advance.
