Hi Alessandro,
Just FYI
I must create a new time series y(t), with 250 observations,
resampling with
replacement the elements of x. I have used the command
genr y = replace(x)
Are you sure that's "replace" and not
"resample" ? ;)
but gretl creates y(t) with 200 observations.
That's
normal. As long as the dataset "dimension" is of 200
observations, no series may contain more than 200 obs.
Can I create y with 250
observations?
You have to add more 50 observations but will not be worth of it : by
resampling x, y series will still contains 200 obs taken from x and 50
obs labelled as NA (not available).
best,
artur
