| Subject | st: lowess with CI with/without controls |
| Date | Thu, 15 Jul 2010 12:58:09 -0400 |
Dear Statlist I am running the following lowess model, and have two questions: lowess y x, bx(.3) 1. Is it possible to graph the lowess smoothing function with confidence intervals? I read in a past thread a recommendation to use bootstrap SEs. http://www.stata.com/statalist/archive/2006-10/msg00651.html .However since `ereturn list' is empty, I am not sure how I can set-up a bootstrap simulation. recommendations for a possible Stata code would be highly appreciated. 2. Secondly, is there an option to run the lowess smoothing of y on x, controlling for X (Matrix of individual-level controls)? Thanks!
