weibull_errorI: Empirical Error Type I Associated with a Weibull Distribution

Description

weibull_errorI is used to obtain an empirical error type I when we use a random sample from a Weibull distribution.

Usage

weibull_errorI(c = 1, n = 150, theta0 = 1, sigma = 1, R = 15000)

Value

A list with number of replicates, sample size, and critical value that were used in the calculation of error type I associated with a likelihood ratio statistic.

Arguments

c

numeric, represents a positive value that defines a critical region. Default value is 1.

n

numeric, represents the size of the sample. Default value is 100.

theta0

numeric, represents the location parameter under the null hypothesis of a sample from a Weibull distribution. Default value is 1.

sigma

numeric, represents the scale parameter of a Weibull distribution. It is assumed known and its default value is 1.

R

numeric, represents the number of replicates. Default value is 15000.
