Dear Statalist,
I have a dependent variable that is continuous
and a set of 20 independent variables that are percentage based, with
the condition that the sum of these variables must be 100% across each
observation. The data is across section only.
I am aware that
interpretting the coefficients from a general OLS fit will be
inaccurate. The increase of one of the 20 variables will have to be
facilitated by a decrease in one or more of the other 19 variables.
Is
there an approach to get consistent coefficient estimates of these
parameters that consider the influence of a proportionate decrease in
one or more of the other 20 variables?
Best,
Nick
