Thank you Scott. I was using something similar, but instead of your proposition The problem with the marginsplot command is, that I cannot combine other graphs as I would like to put graphs of two different models in one plot, i.e. for an unconditional and a conditional model. Hence, I was thinking about qfitci. Any further suggestions? On 25.07.2012 15:49, Scott Merryman wrote:

Essentially, I want to run the following regression: /reg y c.age c.age#c.age i.male i.country_ind/ /num_hh_children income/ I'd like to have the prediction of the age polynomial based on the above regression setting all other variables, respectively, to their base level (factor variables) or zero if continuous. Based on this prediction I need a plot similar to the one produced by /qfitci/. The Stata command /qfitci/ does only allow for one regressor that is used to compute the quadratic prediction.
