Dear All,
Can I use lm() to fit more than one response in
single expression. e.g data is a matrix of these
variables
R1 R2 R3 X1 X2 X3
1 2 1 1 2 3
Now i wnat to fit
R1~X1
R2~X2
R3~X3
in turn, and I don't want to do it use loops
of couse it it easy to make it using loops,but the proceed is very slow since
the data is very big
Can't anybody give me some tips or help, my eamil: guoshicheng2...@yeah.net
No. You will have to iterate in some way. How big can the data be that
this is slow? Anyway, since there may be overhead by calling it via the
formula interface,. you can directly fit using an explicitly given
Design matrix in lm.fit().
Best,
