with continuity correction

Described in Chapter 4 "The 2x2 Table"

Pearson_chi_squared_test_CC_2x2(n)

Arguments

n: the observed counts (a 2x2 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.

Examples
