SIMSTAT: Analysis of proportions
This is chosen when you have y successes in N trials in several
groups and you want to compare the alternative estimates for the
binomial parameter, with exact confidence limits, by statistical and
graphical methods. Consult program BINOMIAL for more details about
the binomial distribution.
You can input a matrix with columns of y and N (as in the test file
binomial.tf2) or you can add a third column for another variable (x,
if the spacing is parametric as in the test file binomial.tf3).
Note that exact error bars are calculated, where you can alter the
default significance level, and data transformed into log odds
for plotting has exact (unsymmetrical) transformed error bars.
If you are interested in comparing proportions across a set you can
request tables for all the differences, ratios (relative risks),
and odds ratios with large sample confidence limits.
In the special case where the data are a 2 by 2 by k set, that is k
sets of adjacent 2 by 2 contingency tables, a Cochran-Mantel-Haenszel
Meta Analysis can be done and the k Log Odds Ratios plotted.
