Method Details

getWithMean

boolean getWithMean()

getWithStd

boolean getWithStd()

validateAndTransformSchema

StructType validateAndTransformSchema(StructType schema)

Validates and transforms the input schema.

withMean

BooleanParam withMean()

Whether to center the data with mean before scaling. It will build a dense output, so take care when applying to sparse input. Default: false

Returns:

(undocumented)

withStd

BooleanParam withStd()

Whether to scale the data to unit standard deviation. Default: true

Returns:

(undocumented)
