Hi,
I discovered what's IMHO a relative severe bug (severe because it can go
unnoticed and would lead to rubbish afterwards):
Missing values are not propagated when multiplying dummy variables. Example:
open greene14_1
series check1 = (Q>100)
series check2 = zeromiss(LF <0.5)
series checkmult = check1*check2
and 'checkmult' should have missings where check2 has them but it doesn't.
I discovered it in a panel context but I haven't tested whether it's
more general than that.
thanks,
sven
