The quantile regression function: When the confidence intervals cannot be computed (I get a "Not a number in calculation" warning, and I instead let gretl compute the standard errors for a tau sequence, the graph with confidence intervals for the tau sequence is still available, giving weird CIs. Further, for the quantile regression function the Gretl User’s Guide says that for large data sets, "If you want confidence intervals in such cases, you are advised not to use the --intervals option, but to compute them using the method of “plus or minus so many standard errors”." It would be great if there was an option to automatically compute and print the CI calculated with this option. E.g. a new radio button in the GUI: "Compute confidence intervals using normality approximation". Best regards and thanks for a GREAT software, Andreas
