Dear, I am doing a time series regression (one dependent time series variable, 7 independent time series variables and 32 annual observations). I have the problem of cointegration, autocorrelation and multicollinearity. I am considering an error correction model of the form: diff(lnY(t))=a+b1*lnY(t-1)+b2*lnX(t-1)+b3*diff(lnX(t))+error and not able to solve all problems. Any suggestion how to built a good model that solves these problems? I appreciate your help. Thanks, Bereket
