simulateCoverageDifferenceTwoProportions: Simulate the coverage of a safe confidence sequence for differences between proportions for a given distribution and safe design.

Description

Simulate the coverage of a safe confidence sequence for differences between proportions for a given distribution and safe design.

Usage

simulateCoverageDifferenceTwoProportions(
  successProbabilityA,
  trueDelta,
  safeDesign,
  precision = 100,
  M = 1000,
  numberForSeed = NA
)

Value

the proportion of simulations where the trueDelta was included in the confidence sequence.

Arguments

successProbabilityA

probability of observing a success in group A.

trueDelta

difference in probability between group A and B.

safeDesign

a safe test design for two proportions retrieved through designSafeTwoProportions().

precision

precision of the grid to search over for the confidence sequence bounds. Default 100.

M

number of simulations to carry out. Default 1000.

numberForSeed

number for seed to set, default NA.

Examples

balancedSafeDesign <- designSafeTwoProportions(na = 1,
                                               nb = 1,
                                               nBlocksPlan = 20)
simulateCoverageDifferenceTwoProportions(successProbabilityA = 0.2,
                                         trueDelta = 0,
                                         safeDesign = balancedSafeDesign,
                                         M = 100,
                                         precision = 20,
                                         numberForSeed = 1082021)
