In SMIR: Companion to Statistical Modelling in R

Description

Follman and Lambert (1989) gave an example of a logistic regression with a varying intercept term. The data consist of numbers $y$ of trypanosomes killed out of $n$ treated at a treatment dose $x$.

Usage

a numeric vector

n

a numeric vector

y

Examples

 data(trypanos)
 library(npmlreg)
 (trypanos.np1 <-  alldist(cbind(y, (n - y)) ~ log(x),
      random =  ~1, data = trypanos, family = binomial,
      plot.opt = 0, verbose = FALSE,k=1))
 (trypanos.np2 <- update(trypanos.np1,k=2))
