ind2x2

Independence 2x2 compositional table

Description

Estimates the expected frequencies from an 2x2 table under the null hypotheses of independence.

Usage

ind2x2(x, margin = 3, pTabMethod = c("dirichlet", "half", "classical"))

Arguments

x

a 2x2 table
margin

if multidimensional table (larger than 2-dimensional), then the margin determines on which dimension the independene tables should be estimated.
pTabMethod

‘classical’ that is function prop.table() from package base or method “half” that add 1/2 to each cell to avoid zero problems.

Value

The independence table(s) with either relative or absolute frequencies.
