Tamaño muestral mínimo y contraste de dos proporciones binomiales.

Abstract

In this paper, we design an algorithm to calculate the minimum sample size for the two-parameter binomial test. We test H0: p1=p2=p0 against Ha: p1=p0−Δ and p2=p0+Δ, 0<Δ<p0≤1/2, with level of significance (type I error) below α and power function above 1−β (type II error below β). We supply tables that define the decision function for testing the two hypotheses.
