// SplitFloat64 provides simple anomaly detection for skewed data sets with no particular distribution.
// In essense it applies the formula if(v > median(values) + threshold * medianAbsoluteDeviation) -> anomaly
// In essence it applies the formula if(v > median(values) + threshold * medianAbsoluteDeviation) -> anomaly
// There's a corner case where there are just 2 values, so by definition there's no value that exceeds the threshold.
// This case is solved by introducing additional value that we know is good, e.g. 0. That helps to improve the detection results
// on such data sets.
