I use proc model to estimate a model such that
alpha=a + b x
eq.one=m *R-1- 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?
