binveR Documentation

Inverts a marginal log-linear parametrization

Description

Inverts a marginal log-linear parametrization.

Usage

binve(eta, C, M, G, maxit = 500, print = FALSE, tol = 1e-10)

Arguments

eta

a vector of dimension t-1 where t is the number of cells of a contingency table.

C

A contrast matrix.

M

A marginalization matrix.

G

G is the model matrix of the loglinear parameterization with no constant term.

maxit

an integer, specifying the maximum number of iterations. Default 500.

print

a logical value: if TRUE, prints the criterion after each cycle.

tol

A small value specifying the tolerance for the convergence criterion. Default: 1e-10.

Details

A marginal log-linear link is defined by \eta = C (M \log p). See Bartolucci et al. (2007).

Value

A vector of probabilities p.

Note

From a Matlab function by A. Forcina, University of Perugia, Italy.
