Transforms a data set by subtracting the column mean from each column and
dividing each column by the square root of its variance when the latter is
sufficiently large in magnitude.
Usage
censcale(x, tol = 0.0001)
Arguments
x
Matrix of observations.
tol
Threshold for column scaling. A column is divided by the square root of its
variance (standard deviation) when that quantity exceeds tol, The default
value is 0.0001.
