st: Re: help with graphing spline effects with continuous moderators

[Maarten Buis <maartenlbuis@gmail.com>]

Such questions need to be sent to statalist and not to individual
members. The reasons for that are explained in the Statalist FAQ, a
link to that can be found at the bottom of every post on Statalist.

The answer to your question can be found here:
