fitted.values in lm function
Hi
i have few clarification regarding the output from the fitted(object).
I'm creating a object using the following formula
dataset <- read.csv("~/data.csv")
obj = lm (formula="log(y+1)~log(x1+1)+(log(x2+1)+log(x3+1)", data=dataset)
fitted(obj)
here the output of the fitted(obj) considers the log(x1+1) or just log(x1).
