\[
A=\begin{bmatrix}
\frac{1}{3} & \frac{1}{3} & \frac{1}{3} \[6pt]
\frac{2}{3} &\frac{-1}{3} &\frac{-1}{3} \[6pt]
\frac{1}{3} & \frac{1}{3} & \frac{-2}{3}
\end{bmatrix}
\]

\[n=\underbrace{1+1+\cdots+1}_{\text{$n$ times}}.\]

Test för R

plotSubset <- data.frame(scale(mdrrDescr[, c("nC", "X4v")])) 
xyplot(nC ~ X4v,
       data = plotSubset,
       groups = mdrrClass, 
       auto.key = list(columns = 2))

Test för Python

from sklearn.feature_selection import VarianceThreshold
X = [[0, 0, 1], [0, 1, 0], [1, 0, 0], [0, 1, 1], [0, 1, 0], [0, 1, 1]]
sel = VarianceThreshold(threshold=(.8 * (1 - .8)))
sel.fit_transform(X)
array([[0, 1],
       [1, 0],
       [0, 0],
       [1, 1],
       [1, 0],
       [1, 1]])
