calculateJB {singR} | R Documentation |
Calculates the sum of the JB scores across all components, useful for determining rho.
Description
We measure non-Gaussianity using Jarque-Bera (JB) statistic, which is a weighted combination of squared skewness and kurtosis, JB paper. The data has to be standardized and mean 0 and sd to 1.
Usage
calculateJB(S = NULL, U = NULL, X = NULL, alpha = 0.8)
Arguments
S |
the variable loadings r x px. |
U |
U matrix for matched columns rj x n |
X |
whitened data matrix n x px, data = whitenerXA %*% dXcentered |
alpha |
JB weighting of skewness and kurtosis. default = 0.8 |
Value
the sum of JB score across all components.
