Computing
Given a set 
,
the problem is to compute the sample means or the
covariance matrix or the correlation matrix:
X
of n
p
-dimensional feature vectors ,
the problem is to compute the sample means or the
covariance matrix or the correlation matrix:Statistic | Definition |
|---|---|
Means |  , where  |
Covariance matrix |  , where  ,  ,  |
Correlation matrix |  , where  , , |
Computation method:
dense
The method computes the means or the
variance-covariance matrix or the correlation matrix
