U-CARE & Jolly-Seber

I hope this is not a stupid question...
In U-CARE's manual it says that GOF test are available for three main models, variants of CJS model (page 16)
Is that mean that I cannot use it to test the hypothesis in JS model? :roll:

Thanx in advance

The difference between the JS and the CJS model is that in the JS model,
the assumption of equal catchability for marked and unmarked animals is made.
This assumption cannot be straightly tested in U-CARE. However, the test of homogeneity
of capture for marked individual can be made.

Thank you very much Rémi.

You and another response helped me a lot.
May I ask you one more question?
Is there a way of checking if my capture recapture data are sufficient, i.e. how many recaptures do I have to make just to be enough for my analysis.
Does U-CARE check this? In my analysis there are tests that don't give results. See an example.
And what if only one test (e.g. 3.sm, 2.cl) don't give results whereas the other two give.

Thank you one more time
