Confidence Intervals on Mark Recapture Estimates

Mark.W.Andrews
Hi All,

I am trying to figure out how to do confidence intervals on a number of
Mark/Recapture exercises. My sample book indicates to that is more
accurate to us a Pearson's Chi-square tests (or likelihood ratios) on a
2 by 2 box

        Yes     No
Yes     x       y
No      z       ???

I need to calculate the range of the missing value at a 95% confidence
interval for a number of cases that are in the format

        Var1    Var2    Var3
Case1   x1      y1      z1
Case2   x2      y2      z2

Also, we have one case where we marked 60 and recaptured none leaving us
with an infinite population estimate. It seems like it should be
possible to estimate the minimum population (at 95% confidence) for this
case. Is this possible?
