Power Analysis and Effect of sample size

Postby ssaps33 » Tue Oct 04, 2011 8:44 pm

Hi!

I have looked through the Help section as well as the manual but haven't found anything on Power analyses. Is it at all possible to do a Power test in MARK?

I have run models but just need a power analysis on it.

Thank you for your help.

Have a look at the latter parts of appendix (1).

In fact, if you'd searched for 'power analysis' on the book as a single PDF file (something I always recommend doing), you'd have found the relevant sections in appendix A right away. Also, you obviously didn't check the index, where 'power analysis' is listed. You may indeed have 'read the manual', but perhaps try a bit harder next time (looking in the index would have seemed a rather obvious thing to do).

Thank you for that.

I read through the section and it talks about running simulations on CJS data. Is it possible to do this with a known-fate model? Is there a way to do a power analysis with survival data/known-fate? Thanks again!

Cheers
