No, but there are 4 cases where J_Heirat==JScheidung, in all other cases J_Heirat < JScheidung

Do you have cases where J_Heirat > JScheidung?

Hopefully somebody can help me out with this:

I am trying to estimate the average marriage time until divorce.
When I run the stset command, I always get the following "probable error":

id: respid
failure event: failed == 1
obs. time interval: (date0, date1]
exit on or before: failure
t for analysis: (time-origin)
origin: time date0
if: partnr==minpart


     7277  total obs.
       10  overlapping records (date1[_n-1]>date0)  PROBABLE ERROR
      468  ignored per request (if(), etc.)


6799 obs. remaining, representing
6799 subjects
1067 failures in single failure-per-subject data
116093.5 total analysis time at risk, at risk from t = 0
earliest observed entry t = 0
last observed exit t = 49

What does Stata mean by "overlapping records (date1[_n-1]>date0)"?
How can I solve the probable error?


gen failed=1
replace failed=0 if JScheidung==.
replace failed=9 if JSterbe <=2000
gen date0= J_Heirat
gen date1= JScheidung
replace date1= 2000 if JScheidung==.
replace date1= JSterbe if JSterbe<=2000
drop if date0==.
drop if date1==.
replace date1=date1+ .5 if date1==date0
sort respid partnr
by respid (partnr): gen minpart=partnr[1]
stset date1, id(respid) time0(date0) origin (time date0) failure (failed==1) if(partnr==minpart)

Thank you!
