Hi all, I have been reading the instructions to graph the clarify results in stata. However, it is not clear how to keep the confidence intervals low and high values for a simple OLS regression instead of a probabilistic model. When I try to do it: estsimp reg dependent set of independents, sims(1000); gen axis=_n + 1 in 1/204; setx mean; local a=1; while `a'<=204 {; setx keyindependent `a'; simqi, ev genpr(margins); _pctile margins, p(.5,99.5); replace plo=r(r1) if axis==`a'; replace phi=r(r2) if axis==`a'; drop margins; local a = `a' + 1; }; sort axis; graph plo phi axis, s(ii) c(||); It returns this message "Probabilities are not allowed with regression", as I understand it when we say genpr(margins) we are just generating the confidence interval and in the next line we define the confidence level, such that we can replace those values to be graphed later. If I try without generating the margins I obtain the values but, obviously, this are not kept by stata and thus I cannot do the graph directly in stata. I wonder if any of you have faced the same problem and how did you solved it.
