Computes the estimators of Hudgens and Halloran (2008) and bounds of Rigdon and Hudgens (2014) for treatment effects on a binary outcome in a twostage randomized experiment with interference
1 
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} 
Function will return many values (to be used by other functions in this package), but the only important value here is tab.eff
tab.eff 
Labeled table of estimates and bounds
