Detailed Description

Calculates the mode of a unidimenensional distribution using the Fraction of Sample Mode with Weights algorithm For reference, see: On a Fast, Robust Estimator of the Mode: Comparisons to Other Robust Estimators with Applications, David R. Bickel, Rudolf Fruehwirth, arXiv:math/0505419 It's like an iterative "Half Sample Mode", but the fraction you take at each step can be configured by the user. Configuration possibilities: (1) fraction (default is 50 %) (2) firstFraction (default is 50 %)
