Calculate Chi Square Statistic

Given two datasets with ordinal variables, computes the chi squared statistic. To obtain the lambda statistic as used in pmc(), subtract the degrees of freedom.

Usage

chi_sq(x, y)

Arguments

x

An object for which a method exists (e.g, data.frame).

y

An object for which a method exists (e.g, data.frame).

Value

numeric

Examples

if (FALSE) { # \dontrun{
if(interactive()){
 chi_sq(iris[1:2], iris[3:4])
}
} # }
