Hi all, I just started to work with R a couple of weeks ago. Right now I would like to regress an independent variable on a couple of explanatory variables. The dependent variable is left censored in the sense that all negative values and zero are set equal to one. This is done because I want to take the logarithm which, as you all know, is only defined for values bigger than zero.
However, what I don't know now is how to compute this on R. Does anybody know how to proceed? I already checked http://cran.r-project.org/web/packages/censReg/vignettes/censReg.pdf <http://cran.r-project.org/web/packages/censReg/vignettes/censReg.pdf> but I am not able to apply the commands shown on page 8 correctly on my data set. Hence, I would really appreciate if somebody could give me a step-by-step instruction for my own dataset. -- View this message in context: http://r.789695.n4.nabble.com/Tobit-model-with-panel-data-tp4689760.html Sent from the R help mailing list archive at Nabble.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.
