Forwarded on behalf of Sebastien Rodrigue-Prive: Here it's my programation with Gretl :
open mensuelmemoire-sanslesnulles-160310 # create big list of variables list biglist = I*EX I*IM # create a list of regresor list reg1list = TREND PRE911 POST911 TX_CHG Jan Fev Mar Avr Mai Juin Juil Aou Sep Oct Nov Dec DICHO_OCT # full results matrix, start empty matrix Res = {} loop foreach i biglist # create multiplicator # diminuer leS VARIABLES ( / 1 000 000) PIB_IND_C_ = PIB_IND_C / 1000000 PIBN_US_ = PIBN_US / 1000000 series $i_def = $i / (PIB_IND_C_ * PIBN_US_) / DEF_US # run the regression ols $i_def 0 reg1list # grab the coefficient and stan-error matrix res = $coeff' | $stderr' # and add to the big results matrix Res = Res | res endloop # open a fil to write down the results outfile "results par un million 100504-1.txt" --write printf "%#12.6g", Res outfile --close Everythings worked very well. The problem it's when I want to get in my res matrix the value of my coefficient and my the value of my critical-p... doesn't work. I tried $pvalue, doesn't work. I really need to get out the critical-p for my presentation. The point it's to change the $stderr' for the acessor that gonna gives me my critical-p. I tried... I could printed out the R-squared, adjusted R-squared, could build square-root testing, but one of the easiest things to do, doesn't work. Thank you very mych S�bastien Rodrigue-Priv� UQ�M
