Hello Allin,
I take this from the gretl-api documentations of your website but there is no documentations for "parms"
quantreg ()

MODEL               quantreg                            (const char *parm,
                                                        const int *list,
                                                        double ***pZ,
                                                        DATAINFO *pdinfo,
                                                        gretlopt opt,
                                                        PRN *prn);

Estimate the model given in list using the method of quantile regression.

parm :
list : model specification: dependent var and regressors.
pZ : pointer to data array.
pdinfo : information on the data set.
opt :
prn :
Returns : a MODEL struct, containing the estimates.

Perhaps the documentations from CVS will be better but i get this when trying to generate it :
