Coding mortalities in POPAN model

Postby cjackson1373 » Tue Apr 19, 2022 1:04 pm

I'm running a model that has a few losses on capture, and I'm having some trouble coding the INP file so that MARK recognizes the mortalities. For example a few lines from my INP file look like:

00001 5;
00010 4;
00001 -1;
00010 -1;

When I run a model, I get a warning message that says, "**WARNING** At least a pair of the encounter histories are duplicates.

When I run the Release GOF test, the CH with negative counts are indicated as "duplicates" and they aren't included in the analysis.

I can't seem to figure out a way to get around this, any help would be appreciated.

This is normal whenever your encounter history (.inp) file has one line per individual (meaning, you might have multiple individuals with the same encounter history). Nothing to worry about...

When I run the Release GOF test, the CH with negative counts are indicated as "duplicates" and they aren't included in the analysis.


Same as above -- normal behaviour...

I can't seem to figure out a way to get around this, any help would be appreciated.

Good news - there is nothing to 'get around'.
