Dear Gretl Community, Please take a look at this script: <script> Eval = fcstats(pib , pib_f) scalar ME = Eval[1,1] scalar MSE = Eval[2,1] scalar MAE = Eval[3,1] scalar MPE = Eval[4,1] scalar MAPE = Eval[5,1] scalar UTheil = Eval[6,1] </script> I'm trying to print the following information: Mean Error (ME) = 0.02 Mean Squared Error (MSE) = 0.001 Mean Absolute Error (MAE) = 0.03 Mean Percentage Error (MPE) = 0.5 Mean Absolute Percentage Error (MAPE) = 0.66 Theil's U = 1.75 Using the following command: <script> print "Mean Error = " ME . . . print "Theil's U = " UTheil </script> But it is not working. Any hints? Best, Henrique C. de Andrade Doutorando em Economia Aplicada Universidade Federal do Rio Grande do Sul www.ufrgs.br/ppge1 Mean Error (ME) 2 Mean Squared Error (MSE) 3 Mean Absolute Error (MAE) 4 Mean Percentage Error (MPE) 5 Mean Absolute Percentage Error (MAPE) 6 Theil's U
