I am running Stata SE/17.0 on a Windows machine with Intel i7 1.8GHz, and 32GB RAM. So not exactly top of the line, but not a "weak" computer either.

My dataset has a smidge over 200,000 observations. Through an if option in my lowess, I am limiting observations to about a smidge over 160,000.

Hit the Ctrl-D for the lowess about a half hour ago, but no indication whether Stata is still running or is hung now. If still running, I wonder how long it might end up taking...

Does lowess take a long time to run?
