pb with unequal time intervals

Postby Gourlay » Wed Jun 08, 2011 10:30 am

Hi,

I am beginning a study investigating movement probability between the breeding season and the wintering in diving ducks. The data consist of two capture sessions each year (4 months during the breeding season from April to July and 2.5 months during wintering from 15 November to 15 January) over a period of 7 years. So essentially we have 14 occasions with unequal time intervals between all of them.

The file to account for unequal time intervals looks like this (monthly estimates)
7.5 4.5 7.5 4.5 7.5 4.5 7.5 4.5 7.5 4.5 7.5 4.5 7.5

I import these files as described in the manual and set the #steps to be “1 2 3”. But none of the models (even the simplest ones) work properly.
I get the following error messages on the black screen:

???Undefined variable ind0
Error in -> EM at 100
Error in -> menumuse>Run_callback at 1337
Error in -> gui_mainfcn at 96
Error in -> menmuse at 45
??? Error while evaluating unicontrol Callback

When I just have equal time intervals throughout the models all run fine.

What is going on?

Thanks,

Marie-Lucile

Which version of E-SURGE do you used ?

I used E-surge V 1.7.1

Did you try to deconnect the EM-Quasi-Newton algorithm ?

Hello,

sorry for this very late reply.

It's ok, the model run !

Thanks a lot,
