Function input for regression analysis
Have you seen the lm() function? I think it does what you are talking about, but the vagueries of your statement make it hard for me to give a concrete answer. It does worry me to think of you having one function to do all your regressions analysis ever for any problem whatsoever.... Michael

Dear all,
I have a small question.
I would like to write a function for a regression analysis that an be
applied to every dataset.
Now my problem is that I do not know what I have to implement then as input
for the function
mytest <- function (x,y) {
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?beta <- solve(t(x)%*%x%*%t(x)%*%y
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?(....)
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? }
would not make any sense, because then you could only use a dataset with y
and one predictor,
but I just dont know how to do this in another way.
Has someone any idea?
Thanks a lot!
Cheers, Maria
