Hello. I can't figure the following thing out myself (poor API documentation), what the order of values in *const int *list *is in MODEL <http://gretl.sourceforge.net/API/gretl-libgretl.html#MODEL:CAPS> arma (*const int *list*, *const int *pqlags*, *const double **Z*, *const DATAINFO <http://gretl.sourceforge.net/API/gretl-libgretl.html#DATAINFO:CAPS> *pdinfo*, *gretlopt <http://gretl.sourceforge.net/API/gretl-libgretl.html#gretlopt> opt*, *PRN <http://gretl.sourceforge.net/API/gretl-PRN.html#PRN:CAPS> *prn*); I say, p is 2, q is 2 and d is 0, dependent variable is #2, no exogenous regressors. list[0] - autogenerated, list[1] = 2, list[2] = 2, list[3] = 2, right? Besides, can you explain the meaning of fields in FITRESID structure? Particularly, what is the forecast actually, FITRESID.double *actual or FITRESID.double *fitted? Thanks, Makovtsev Vadim.
