protected Ball(List<Event> ballData)

Creates a ball from the given data - for case where no more split is needed

参数:

ballData -

Ball

protected Ball(double[] ll,
               double[] ur,
               Event event,
               int numPoints,
               Ball leftBall,
               Ball rightBall,
               double minBW,
               double maxBW)

Creating a Ball on split, saving all necessary sufficient statistics for the region.

参数:

ll - - Lower left corner of the region

ur - - Upper right corner of the region

event - - The data point on which we split

numPoints - - #Points in that region

leftBall - - Left child

rightBall - - Right Child

minBW - - Minimum BW in that region

maxBW - - Maximum BW in that region
