Class ParamTendenciesStat

java.lang.Object
  stat.Stat
      stat.ParamTendenciesStat

All Implemented Interfaces:

MoreMath.Comparer, java.lang.Runnable

public class ParamTendenciesStat

extends Stat

implements java.lang.Runnable, MoreMath.Comparer

Saves a parameter set with the minimum and maximum values set to encompass the most common values for each parameter in all the loaded sets. The statistic uses the following algorithm to find those ranges: First it sorts all the values for a parameter from all the parameter sets from lowest to highest. Then it finds the the position that is proportionIncluded along the list (for instance, if proportionIncluded is 0.5 and there are 100 parameter sets then it finds the value at position 50). It stores the ratio of the value at this position divided by the value at position 1. It then moves up one position, and finds the ratio between the two values starting at the new position (ratio of position 51 to position 2 in example). It keeps going till it reaches the end of the list, always storing the smallest ratio found. It then saves out a minimum and maximum corresponding to where that smallest ratio was found - this min and max will then encompass the most concentrated proportionIncluded of the values in the set. If the smallest ratio was below minRestriction, it saves out a minimum value at the minimum value found for the lowest ratio, but a maximum value that is minRestriction times that minimum value (thus, the range is never less than minRestriction). If the smallest ratio is more than maxRestriction, it saves out the full original range with no restriction.

Blech. It might be easier just to read the code. This needs some work, anyway.
