Dear all,
I would like to fit an lm in which a subset of the explanatory variables
are linearly dependent. Thus I would like to include the restriction that
all betas of these variables sum to 1. Is there a way to this in R? Or is
this what happens automatically if I set singular.ok= T (which is the
default, I believe)?
Thanks for your help. Lorenz
