Quantile scores as dependent variables.. an R and general method question

The OP is looking for a way to deal with outcomes scores that are quantiles, not a method that models different quantiles of the conditional distribution where an outcome is a continuous variable. So, I don't think QR methods is what is needed.
Huhh? First, "deal with" is rather vague, does it mean summary? plot? delete? as the OP is worried about independence, some modelling exercise is more likely. Second, where do you think the OP quantiles come from if not from the conditional distribution of some continuous RV ? hint: not France. So for "...leads to theory, texts or R code.." on the distributional properties of quantiles/order statistics, do you have a better suggestion for a starting point than QR methods? Cheers

Clearly these observations are dependent (in that you can't alter one observation without also altering others). Are there methods for dealing with quantile dependent variables. My atempt to find such methods has not bee successful. Really? because google found 227k hits for "R quantile regression" - none of them lead anywhere ? Any leads to theory, texts or R code would be most appeciated. ? ? ? ?[[alternative HTML version deleted]] ______________________________________________ R-help at 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. ______________________________________________ R-help at 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.
