        pulse.search.statistics.BICStatistic

All Implemented Interfaces:

Serializable, Descriptive, Reflexive
```
public class BICStatistic
extends ModelSelectionCriterion
```
Bayesian Information Criterion (BIC) algorithm formulated for the Gaussian distribution of residuals. This is used in model selection. BIC values are always negative. The absolute BIC value is meaningless, it is only used as a comparative statistic.
