validateAndTransformSchema

StructType validateAndTransformSchema(StructType schema)

Validates and transforms the input schema.

withCentering

BooleanParam withCentering()

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

Returns:

(undocumented)

withScaling

BooleanParam withScaling()

Whether to scale the data to quantile range. Default: true

Returns:

(undocumented)
