lambda R Documentation
Calculates Lambda, a measure of association for a cross-tabulation.
Description
Given a table of conditional frequencies, the lambda function calculates and returns Lambda, a measure of association between two categorical variables (factors). Lambda is equal to the proportion of errors reduced by knowledge of the independent variable.
Usage
lambda(tab, digits = 3, detailed = FALSE)
Arguments
tab
The conditional frequencies of a cross-tabulation. The dependent variable should correspond to rows and the independent variable, to columns.
digits
Number of decimal places of Lambda reported (defaults to 3).
detailed
Do you want detailed report on how lambda value calculated? (default is FALSE).
Value
Returns the value of Lambda.
Examples
library(RCPA3)
conditional.frequencies <- table(dv=states$lgbtq.equality.3cat, iv=states$religiosity3)
lambda(tab=conditional.frequencies, detailed=TRUE)
