Jacqueline,
This should be a simple application of GLM. Check the help pages for glm,
family and dose.p in library MASS. Look at the example at the bottom of
the dose.p help page - it does almost exactly what you need.
Hope this helps,
Andy

>-----------------------------------------------------------------------------------------------------------------------------|
Hello all,
I have a very simple set of data and I would like to analyze them with
probit analysis.
The data are:
X Event Trial
100 8 8
75 8 8
50 6 8
25 4 8
10 2 8
0 0 8
I want to estimate the value of X that will give a 95% hit rate
(Event/Trial) and the corresponding
95% CI. Anyone can offer some help? Thanks!!
- Jacqueline
