Example
From Kramer and Burnham (1947).
We have two types of data, F
coupling and F
repulsion.

We can combine estimates from the product of M.L. methods. The method
of maximum likelihood was used to obtain the estimates of p from each
type of family.

combined p value by weighting = 
= 398.94 + 1642.41
= 1635.0 + 5164.8
= 2041.35
= 6799.80
= 0.3002
The standard error of this combined 
is:
