Description

Computes the Lobato and Velasco's statistic. This test proves a normality assumption in correlated data employing the skewness-kurtosis test statistic, but studentized by standard error estimates that are consistent under serial dependence of the observations.

Usage

Arguments

y

a numeric vector or an object of the ts class containing a stationary time series.

c

Details

Value

A real value with the Lobato and Velasco test's statistic.
