[Gretl-users] scalar in loop condition

Hi folks, The following has me at a complete loss. This script runs fine: \begin{script} # program to perform calculations in problem 1.2 of Davidson & MacKinnon nlist = {10; 100; 1000; 10000} n = rows(nlist) means = zeros(n,2) loop i=1..n --quiet jnk1 = cauchy(nlist[i]) jnk2 = mnormal(nlist[i],1) means[i,] = {meanc(jnk1), meanc(jnk2)} endloop print means \end{script} ("Cauchy" is a function I wrote - see attached). However, when I try to run the following one, I get an error saying "undefined variable nreps in loop condition". This happens even though the script output says "generated scalar nreps = 1:" \begin{script} n = 25; # sample size nreps = 1; # number of replications beta1 = 1; beta2 = 0.8; # true values of parameters b1 = 0; b2 = 0; nulldata n loop ii=1..nreps # simulate data series y = zeros(n,1) series u = normal() #y[1] = beta1 + u[1] loop jj=2..n --quiet y[jj] = beta1 + beta2[jj-1] + u[jj] endloop series y1 = y(-1) # run regression ols y 0 y1 b1 = b1 + $coeff(1) b2 = b2 + $coeff(2) print b1 b2 endloop \end{script} I've attached both scripts. Note that I've just started on ETM_3_1, so there may well be other errors (still getting used to gretl scripts). I can't for the life of me figure out why either both work or both don't run. I'm using gretl 1.8.7 on WinXP. TIA, PS =============================== Dr. Peter Summers Assistant Professor Department of Economics Texas Tech University ===============================
