biv.binom

Marginal Bivariate Binomial Regression Models

Description

biv.binom fits (logit) linear regression models to a marginal bivariate binomial distribution. The covariates must be of length K, that is the number of 2x2 tables.

Usage

biv.binom(freq, marg1 = ~1, marg2 = ~1, interaction = ~1,
  pmarg1 = 1, pmarg2 = 1, pinteraction = 1, print.level = 0,
  typsize = abs(p), ndigit = 10, gradtol = 1e-05, stepmax = 10 *
  sqrt(p %*% p), steptol = 1e-05, iterlim = 100, fscale = 1)

Arguments

`freq`	A four-column matrix containing K 2x2 frequency tables.
`marg1`	The model formula for the first margin.
`marg2`	The model formula for the second margin.
`interaction`	The model formula for the interaction.
`pmarg1`	Initial parameter estimates for the first margin regression.
`pmarg2`	Initial parameter estimates for the second margin regression.
`pinteraction`	Initial parameter estimates for the interaction regression.
`print.level`	Arguments for nlm.
`typsize`	Arguments for nlm.
`ndigit`	Arguments for nlm.
`gradtol`	Arguments for nlm.
`stepmax`	Arguments for nlm.
`steptol`	Arguments for nlm.
`iterlim`	Arguments for nlm.
`fscale`	Arguments for nlm.

Value

A list of class bivbinom is returned.

Examples

# 5 2x2 tables
Freq <- matrix(rpois(20,10),ncol=4)
x <- c(6,8,10,12,14)
print(z <- biv.binom(Freq,marg1=~x,marg2=~x,inter=~x,pmarg1=c(-2,0.08),
	pmarg2=c(-2,0.1),pinter=c(3,0)))
