Re: st: mlowess- Rescaling the Y-axis

[Nick Cox <njcoxstata@gmail.com>]

-mlowess- (SSC) is user-written, as you are asked to explain.

To get what you want you would need to clone -mlowess- and remove all  
the graphics calls except those drawing the predicted values given the  
predictors.

If they are essentially flat w.r.t. the predictors the modelling or  
smoothing exercise is evidently finding little structure in the data.
