test.HJM: Henze-Jimenes-Gamero-Meintanis test of multivariate normality
Description
Computes the test statistic of the Henze-Jimenes-Gamero-Meintanis test.
Usage
test.HJM(data, a = 1.5, MC.rep = 500, alpha = 0.05)
Arguments
data
a n x d matrix of d dimensional data vectors.
a
positive numeric number (tuning parameter).
MC.rep
number of repetitions for the Monte Carlo simulation of the critical value.
alpha
level of significance of the test.
Value
a list containing the value of the test statistic, the approximated critical value and a test decision on the significance level alpha:
$Test
name of the test.
$param
value tuning parameter.
$Test.value
the value of the test statistic.
$cv
the approximated critical value.
$Decision
the comparison of the critical value and the value of the test statistic.
Details
This functions evaluates the teststatistic with the given data and the specified tuning parameter a.
Each row of the data Matrix contains one of the n (multivariate) sample with dimension d. To ensure that the computation works properly
\(n \ge d+1\) is needed. If that is not the case the test returns an error.
