# estbound: Estimates and bounds for treatment effects on a binary... In interferenceCI: Exact Confidence Intervals in the Presence of Interference

## Description

Computes the estimators of Hudgens and Halloran (2008) and bounds of Rigdon and Hudgens (2014) for treatment effects on a binary outcome in a two-stage randomized experiment with interference

## Usage

 1 estbound(g, data, m.a0, m.a1) 

## Arguments

 g 1st stage of randomization vector where element i=1,…,k is equal to 1 if group i was randomized to strategy α_{1} and 0 if randomized to strategy α_{0} data 2 \times 2\times k array of 2 \times 2 table data where row 1 is treatment=yes, row 2 is treatment=no, column 1 is outcome=yes, and column 2 is outcome=no m.a0 α_{0} randomization vector where element i=1,…,k is equal to the number of subjects in group i who would receive treatment if group i was randomized to strategy α_{0} m.a1 α_{1} randomization vector where element i=1,…,k is equal to the number of subjects in group i who would receive treatment if group i was randomized to strategy α_{1}

## Details

Function will return many values (to be used by other functions in this package), but the only important value here is tab.eff

## Value

 tab.eff Labeled table of estimates and bounds
