The gamma coefficient

Described in Chapter 7 "The rxc Table"

gamma_coefficient_rxc(n)

Arguments

n

the observed table (an rxc matrix)

Value

An object of the contingencytables_result class, basically a subclass of base::list(). Use the utils::str() function to see the specific elements returned.
