Statistic of the EHS test based on a multivariate Stein equation
Description
Computes the test statistic of the EHS test based on a multivariate Stein equation.
Usage
EHS(data, a = 1)
Arguments
data |
a (d,n) numeric matrix containing the data. |
a |
positive numeric number (tuning parameter). |
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.
Note that a=Inf
returns the limiting test statistic with value 2*MSkew + MRSSkew
and a=0
returns the value of the limit statistic
T_{n,0}=\frac{d}{2}-2^{\frac{d}{2}+1}\frac{1}{n}\sum_{j=1}^n\|Y_{n,j}\|^2\exp(-\frac{\|Y_{n,j}\|^2}{2}).
Value
The value of the test statistic.
