Dear list, I used rqss() in quantreg package for a piecewise linear regression. Can someone tell me how to find the x values corresponding to the breakpoints and the slopes for the phases before and after the breakpoints? I searched the list and gather that there is another package "segmented" that does that, but my stat is pathetic, and I have difficulty setting the parameters right in there. So if there is a way to do that in the quantreg package, I would really appreciate it. Thanks! zy [[alternative HTML version deleted]]
