Hi Greg,
you can use the extension package 'drc' from CRAN:
conc - c(10.3, 10.8, 11.6, 13.2, 15.8, 20.1) # Exposure concentrations
orign - c(76, 79, 77, 76, 78, 77) # Original number of subjects
ndead - c(16, 22, 40, 69, 78, 77) # Number dead after 96 h
d - data.frame(conc=conc, orign=orign,
If you run this you get sensible output, but whether it meets you
needs depends on what you meant by Exp(1):
Y - rnorm(100)
Z - rnorm(100)
X - exp(Y+Z)
hist(X)
