Extract the expected number of tests from testing configuration results

Extract the expected number of tests from objects of class "halving" returned by halving (halving).

# S3 method for class 'halving'
ExpTests(object, ...)

Arguments

object: An object of class "halving", from which the expected number of tests is to be extracted.
...: Additional arguments to be passed to ExpTests (e.g., digits to be passed to round for appropriate rounding).

Value

A data frame containing the columns:

ExpTests: the expected number of tests required to decode all individuals in the algorithm.
ExpTestsPerIndividual: the expected number of tests per individual.
PercentReductionTests: The percent reduction in the number of tests; 100 * (1 - ExpTestsPerIndividual).
PercentIncreaseTestCap: The percent increase in testing capacity when the algorithm is applied to a continuous stream of specimens; 100 * (1/ExpTestsPerIndividual - 1).
