Hello! Just would like to make sure I am not doing something wrong. I am running an OLS regression. I have several subgroups in the data set (locations) - and in each location I have weekly data for 2 years - on my DV and on all predictors. Looks like this:
location week DV Predictor1 Predictor 2 location1 week1 xxx xxxxxxx xxxxxxxxx location1 week2 xxx xxxxxxx xxxxxxxxx . . . location2 week1 xxx xxxxxxx xxxxxxxxx location2 week2 xxx xxxxxxx xxxxxxxxx My DV variable was mean-centered - for each location and I am using this mean-centered DV as the DV in lm. Also, I am using the mean of each location as a weight when I run this regression. Would it still be correct to calculate pcse for this regression? I am not sure because pcse uses the group identifier - so am I not somehow double-counting things? Thank you very much! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
