In Surrogate: Evaluation of Surrogate Endpoints in Clinical Trials

Examine restrictions in \bold{\pi}_{f} under different montonicity assumptions for binary S and T

Description

The function Restrictions.BinBin gives an overview of the restrictions in \bold{\pi}_{f} under different assumptions regarding montonicity when both S and T are binary.

Usage

Restrictions.BinBin(pi1_1_, pi1_0_, pi_1_1, pi_1_0, pi0_1_, pi_0_1)

Arguments

pi1_1_	A scalar that contains P(T=1,S=1|Z=0), i.e., the proability that S=T=1 when under treatment Z=0.
pi1_0_	A scalar that contains P(T=1,S=0|Z=0).
pi_1_1	A scalar that contains P(T=1,S=1|Z=1).
pi_1_0	A scalar that contains P(T=1,S=0|Z=1).
pi0_1_	A scalar that contains P(T=0,S=1|Z=0).
pi_0_1	A scalar that contains P(T=0,S=1|Z=1).

Value

An overview of the restrictions for the freely varying parameters imposed by the data is provided
