Class ProbabilityResult

java.lang.Object
jline.solvers.mva.ProbabilityResult
public class ProbabilityResult extends Object
Result class for probability calculations in solvers.

Supports both scalar probabilities (single value) and probability distributions (vectors/matrices) for marginal and aggregated state probabilities.

For marginal probabilities (getProbMarg), the probability vector contains P(n jobs of class r) for n=0,1,...,N where N is the population.

For aggregated probabilities (getProbAggr), the probability is a scalar representing P(n1 jobs of class 1, n2 jobs of class 2, ...).
