computeConfidenceBoundsForDifferenceTwoProportions: Estimate Lower and Upper Bounds on the Confidence Sequence (Interval) for the Difference Divergence Measure for Two Proportions

Description

Estimate Lower and Upper Bounds on the Confidence Sequence (Interval) for the Difference Divergence Measure for Two Proportions

Usage

computeConfidenceBoundsForDifferenceTwoProportions(
  ya,
  yb,
  precision,
  safeDesign
)

Value

list with found lower and upper bound.

Arguments

ya

positive observations/ events per data block in group a: a numeric with integer values between (and including) 0 and na, the number of observations in group a per block.

yb

positive observations/ events per data block in group b: a numeric with integer values between (and including) 0 and nb, the number of observations in group b per block.

precision

precision of the grid of differences to search over for the lower and upper bounds.

safeDesign

a 'safeDesign' object obtained through designSafeTwoProportions

Examples

balancedSafeDesign <- designSafeTwoProportions(na = 1,
                                               nb = 1,
                                               nBlocksPlan = 10,
                                               alpha = 0.05)
ya <- c(1,1,1,1,1,1,1,1,0,1)
yb <- c(0,0,0,0,1,0,0,0,0,0)
computeConfidenceBoundsForDifferenceTwoProportions(ya = ya,
                                               yb = yb,
                                               precision = 20,
                                               safeDesign = balancedSafeDesign)
