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

In CCd: The Cauchy-Cacoullos (Discrete Cauchy) Distribution

Log-likelihood ratio test for zero location parameter

Description

Log-likelihood ratio test for zero location parameter.

Usage

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

Arguments

y	A vector with integer values.
tol	The tolerance value to terminate the maximization algorithm.

Details

We perform a log-likelihood ratio test to test whether the location parameter can be assumed zero or not.

Value

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