Dear Gretl Team,
I think I found a little error in the example of the "printf" command help:
<hansl>
ols 1 0 2 3
genr b = $coeff(2)
genr se_b = $stderr(2)
printf "b = %.8g, standard error %.8g, t = %.4f\n", b, se_b, b/se_b
</hansl>
If we use "[ ]" instead of "( )" the error goes away :-)
Um abraço,
Henrique Andrade*
