laplace.test: Goodness-of-fit Test Statistics for the Laplace Distribution

Description

Goodness-of-fit test statistics A2 (Anderson--Darling), W2 (Cramer--von Mises), U2 (Watson), D (Kolmogorov--Smirnov), and V (Kuiper). By default, NAs are omitted. For the tables of critical values, see Stephens_1986;textuallawstat and Puig_Stephens_2000;textuallawstat.

Usage

Arguments

y

A2

the Anderson--Darling statistic.

W2

the Cramer--von Mises statistic.

U2

the Watson statistic.

D

## [1] 0.9177726
## The critical value at the 0.05 significance level is approximately 0.906.
## Thus, the null hypothesis should be rejected at the 0.05 level.
