loc0.test: Log-likelihood ratio test for zero location parameter

Description

Log-likelihood ratio test for zero location parameter.

Usage

loc0.test(y, tol = 1e-7)

Value

A vector with the test statistic and its associated p-value.

Arguments

y

A vector with integer values.

tol

The tolerance value to terminate the maximization algorithm.
