Assocs: Association Measures

Description

Collects a bunch of association measures for nominal and ordinal data.

Usage

Assocs(x, conf.level = 0.95, digits = 4)

Arguments

x

a 2 dimensional contingency table or a matrix.

conf.level

confidence level of the interval. If set to NA (which is the default) no confidence interval will be calculated.

digits

integer which determines the number of digits used in formatting the measures of association.

Value

• numeric matrix, dimension [1:17, 1:3] the first column contains the estimate, the second the lower confidence interval, the third the upper one.

Details

This function wraps the association measures phi, contingency coefficient, Cramer's V, Goodman Kruskal's Gamma, Kendall's Tau-b, Stuart's Tau-c, Somers' Delta, Pearson and Spearman correlation, Guttman's Lambda, Theil's Uncertainty Coefficient and the mutual information.
