I think you're right, Artur. Thanks also for reminding us/me of the --weight option of the 'summary' command. So I think what we have in gretl for weighing stuff is:

- 'summary ... --weight' (but this weighs the observations, not the variables, I think)

- the functions wmean(), wvar(), wsd()

- the 'wls' command, as mentioned before

Maybe there's more.

thanks
