La construcción de intervalos de confianza para la estimación de pi_1 − pi_2, la diferencia entre dos proporciones, es un problema importante en el trabajo estadístico aplicado. Revisamos diferentes procedimientos de construcción y mediante un estudio de simulación los analizamos. Proponemos un índice para comparar los distintos métodos, analizando tanto los niveles de confianza reales, como las longitudes de los intervalos.
The construction of confidence intervals to estimate pi_1−pi_2, the difference of two proportions, is an important problem in applied work. We review different methods to construct them and we analyze their performance by a simulation study. Also we propose an index that allows us to compare these procedures, analyzing simultaneously the real confidence level and the length of them.
