public class StandardScaler extends Object
The "unit std" is computed using the corrected sample standard deviation (https://en.wikipedia.org/wiki/Standard_deviation#Corrected_sample_standard_deviation), which is computed as the square root of the unbiased sample variance.
param: withMean False by default. Centers the data with mean before scaling. It will build a dense output, so take care when applying to sparse input. param: withStd True by default. Scales the data to unit standard deviation.
