## Comment on Live Example -1

Hello sir

I have a doubt. Are the regression parameters “static” or “dynamic” in your basic excel tracker sheet? As we know these estimators (coefficients, std. error….) have variance. Everytime we regress the securities the values of the estimators get varied. So taking the parameters of the eqn. y=mx+c as constant and calculating Z-Score based on earlier calculated estimators might give some error, i guess.

What is your view, sir?

Thank you very much for this most awaited chapter, sir!
