Hello, I uesd Dr. Koenker's code on the following website for quantile regression of longitudinal data:
http://www.econ.uiuc.edu/~roger/research/panel/rq.fit.panel.R I can run the code when there are three explanatory variables in X matrix (ncol(X)=4, because there is a vector "1" at the first colume). However, when I increase the number of explanatory variables to four or more than four, R showed me an error message "local(x, pivot, ...) : Increase tmpmax." Could I please ask, how do I deal with this problems? By the way, I set w=c(.1,.2,.3,.4,.5,.4,.3,.2,.1),taus=(1:9)/10, and lambda=1. Many thanks for help. -- Chu, Hao-pang, Graduate Department of Economics National Chengchi University e-mail:97258...@nccu.edu.tw ______________________________________________ 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.
