Package edu.cmu.tetrad.data

Class ContinuousDiscretizationSpec

java.lang.Object

edu.cmu.tetrad.data.ContinuousDiscretizationSpec

All Implemented Interfaces:

DiscretizationSpec, TetradSerializable, Serializable

public final class ContinuousDiscretizationSpec
extends Object
implements TetradSerializable, DiscretizationSpec

Specifies how a column (continuous or discrete) should be discretized. For a discrete column the mapping is int[] remap; for a continuous column the mapping is double[] cutoffs. The categories are the string labels for the categories. This is just a small immutable class that columns can map to in order to remember how discretizations were done so that the user doesn't have to keep typing in information over and over again.
