Enclosing class:

DispersionTask

public static class DispersionTask.ComputeTweedieConstTsk
extends water.MRTask<DispersionTask.ComputeTweedieConstTsk>

Class to pre-calculate constants assocated with the following processes: 1. maximum term index: jMaxConst (col 0) different between p < 2 and p > 2 2. constant term associated with z: zConst, different between p < 2 and p > 2 3. log likelihood: part2Const (col 1), same for all p 4. log 1/y for 12 5. dlogf/dphi firstOrderDerivConst, same for all p 6. d2logf/dphi2 secondOrderDerivConst, same for all p In addition, we also have maximum term with maximum index: logMaxConst, not part of constFrame.
