I removed the first bracket, but the error message is still the same: may
not use noninteger frequency weights
stset tfp [fweight = gew], id(hhnrakt) f(des=2 4 6 8 10 12) exit(time .)

You did not follow my advice to look at the examples. You only removed the
last bracket; the beginning "[" of the second pair remains.

Thanks for your advice. If I remove the brackets, I get the following error
message may not use noninteger frequency weights. I don't understand it,
because fweights are allowed in the stset-command. 
The do-file:
stset tfp [fweight=gew] [ ,id(hhnrakt) f(des=2 4 6 8 10 12) exit(time.)

I should add that in the -help- for -stset-, the brackets indicate where
options, if any, should go. Before running an unfamiliar command, always
look at the examples at the bottom of the help screen or in the manual.

Steve

Remove the second pair of brackets in your -stset- statement. They are not
legal Stata syntax.

Sorry for the impatientness, but I have to solve the problem very soon. 
The case:
- 4841 subjects with multiple record per subject (max 4 records)
- for each subject exists a weight, which identifies the real abundance
pattern in time

I used the following do-file: 
gen des =tfin~=ti

gen tf = tfin-tstart+1

gen org=1+2*(spell-1)
replace des=org
replace des=org+1 if tfin<ti
gen tfc=tstart if spell==1
replace tfc=tfc[_n-1] if spell~=1 & hhnrakt==hhnrakt[_n-1]
gen tsp = tstart-tfc
gen tfp = tfin-tfc+1
stset tfp [fweight=gew] [ ,id(hhnrakt) f(des=2 4 6 8 10 12) exit(time .)]  

Thanks for your support.

Jette, can you provide a reproducible example? That may help diagnose
your problem. Can you reproduce the error with -sysuse- data or
provide your console output, please?

Also, it may take more than a few hours to get a response given
different time zones and work schedule.
