Constructor Detail

PopulationUnitWithUnequalInclusionProbability

public PopulationUnitWithUnequalInclusionProbability(Matrix obs,
                                                     double inclusionProbability)

Constructor. IMPORTANT: the inclusion probability is the individual inclusion probability of this unit. For instance, that would be the area of the plot divided by the total area, and not the plot area multiplied by the sample size. This product is actually handled internally.

Parameters:

obs - the response that was observed in the unit.

inclusionProbability - the probability that this unit is part of the sample.

Method Detail

getInclusionProbability

public double getInclusionProbability()

This method returns the sampling probability of this population unit.

Returns:

a double
