In RI2by2: Randomization Inference for Treatment Effects on a Binary Outcome

Attributable effects based confidence interval for a treatment effect on a binary outcome

Description

Computes the attributable effects based confidence interval for the average treatment effect on a binary outcome in an experiment where m of n individuals are randomized to treatment by design.

Usage

AE.CI(data, level)

Arguments

data	observed 2 by 2 table in matrix form where row 1 is the treatment assignment Z=1 and column 1 is the binary outcome Y=1
level	significance level of hypothesis tests, i.e., method yields a 100(1-level)% confidence interval

Details

The attributable effects based confidence interval from inverting n+2 hypothesis tests.

Value

tau.hat	estimated average treatment effect
lower	lower bound of confidence interval
upper	upper bound of confidence interval
