screening
Returns the screening intervals for each alternative assuming the specified direction of optimization. Returns a map of maps. The keys for the maps are the indices of the alternatives (in combination). The interval represents the screening interval. The intervals are one-sided negative infinity, upper limit for minimization and lower limit, positive infinity for maximization. The intervals can be checked to determine if the alternative should be retained after screening.

Parameters
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.
is the probability of correct selection for the screening.
the indifference zone parameter. If the systems are within this value, then we are indifferent to the difference. The default is 0.0.
the type of optimization {MINIMIZE or MAXIMIZE}. The default is MINIMIZE.
