Class StoredCellProbsObs

java.lang.Object
edu.cmu.tetrad.bayes.StoredCellProbsObs
All Implemented Interfaces:
TetradSerializable, Serializable
public final class StoredCellProbsObs extends Object implements TetradSerializable

Creates a table of stored cell probabilities for the given list of variables. Since for a moderate number of variables and for a moderate number of values per variables this could get to be a very large table, it might not be a good idea to use this class except for unit testing.> 0
