Hi again,
OK let's see if this one qualifies as a bug:
<hansl>
clear
T = 200
N = 20
len = T*N
nulldata len --preserve
setobs T 1:1 --stacked-time-series
eval $panelpd # gives 0
</hansl>
The zero $panelpd value is in contrast to the documentation, which says:
"If the periodicity is not set in the active panel dataset, returns 1 in
analogy to $pd for cross-sectional or undated data."
In the meantime I have updated to the latest snapshot.
thanks
sven
