Class ShiftSearch

java.lang.Object

edu.cmu.tetrad.search.utils.ShiftSearch

public class ShiftSearch
extends Object

Tries to find a good shifting of variables to minimize average BIC for time-series data. The idea is that the data one is presented with may have the variables temporally shifted with respect to one another. ShiftSearch attempts to find a shifting of the variables that reduces this temporal shifting.
