Nest age effects on nest survival

[carina]

I am new to program MARK and am trying to do a nest survival analysis. My data is set up in the same format as Dinsmore et al. (2002), with values for k, l, m, f, freq., followed by 73 covariates for daily nest age (the length of the nesting season).

I have successfully estimated overall daily nest survival S(.) and the effect of year only S(year). Now I am trying to determine if there is an effect of nest age on daily nest survival. How do I set up my Design Matrix to answer this question?

I did it this way:
B1 B2
1 Age1
1 Age2
1 Age3
...
1 Age73

But if this is correct, I'm confused. When I run this matrix, I get 73 survival estimates, but what I really want are 22 estimates (the length of their nesting cycle, NOT the length of the nesting season). Clearly I don't have a good understanding of the Design Matrix.

I would appreciate any help.
