I use proc model to estimate a model such that

alpha=a + b x

moments are:

eq.one=m *R-1- alpha;

eq.two=m*R*Z-Z-alpha;

I want to estimate parameters a and b. but the results is biased. I find in SAS help that biased results are due to the model equation. it is such that there is linear dependency that causes biased results and inflated variances

Can someone help me?

I think we need more information here.  Can you share your PROC MODEL code?
