StandardScaler

object StandardScaler extends SettingsBuilder
Transform features by normalizing each feature to have unit standard deviation and/or zero
mean. When withStd is true, it scales the data to unit standard deviation. When withMean is
true, it centers the data with mean before scaling.
Missing values are transformed to 0.0 if withMean is true or population mean otherwise.
