constraints: Calculate the matrix constraints

In mpiktas/retacoro: Recover Table Given Column And Row Totals

Description

Calculate the matrix constraints

Usage

constraints(a, ratio = c("fixed", "sequential"))

Arguments

a	the matrix
ratio	a string specifying the type of ratios used. The default is "fixed" for ratios with fixed first row and column. It is also possible to use "sequential" ratios

Value

a list with the following elements

cs	the vector of column sums
rs	the vector of row sums without the last element
p	the vector of likelihood ratios
A	the constraint matrix for sums without the last row
B	the constraint matrix for log-likelihood ratios

Examples

m <- matrix(1:20, nrow = 5)
constraints(m)
