fun screenAlternatives(groups: List<EstimatedResponseIfc>, probCS: Double = DEFAULT_CONFIDENCE_LEVEL, indifferenceZone: Double = 0.0, optimizationType: OptimizationType = OptimizationType.MINIMIZE): Set<Int>(source)

Screens for the best from the set of alternatives using the specified probability of correct selection probCS. Returns the set of alternatives that could be the best. with the specified probability of correct selection.

Based on: Nelson et al. (2001) “Simple Procedures for Selecting the Best System when the Number of Alternatives is Large,” Operations Research, vol. 49, pp.950-963.

Return

A set containing the indices of the alternatives that are not screened. The indices are zero-based.

Parameters

groups

the groups to be screened. The group's size must be 2 or more. The sample size for each group must be two or more.

probCS

is the probability of correct selection for the screening.

indifferenceZone

the indifference zone parameter. If the systems are within this value, then we are indifferent to the difference. The default is 0.0.

optimizationType

the type of optimization {MINIMIZE or MAXIMIZE}. The default is MINIMIZE.
