Muestreo en dos ocasiones sucesivas bajo un diseño por conglomerados
I. Oña Casado, A. V. García Luengo
El muestreo por conglomerados se utiliza ampliamente, debido a su bajo coste y ahorro de tiempo, para realizar encuestas complicadas y a gran escala.
En este trabajo, con un muestreo en dos ocasiones, hemos estudiado un estimador lineal del promedio para la ocasión actual, cuando las unidades han sido elegidas bajo un diseño de muestreo por conglomerados. Las observaciones de la primera ocasión se utilizan como información auxiliar para las observaciones de la segunda ocasión o de la actual. A dicho estimador del promedio le imponemos las condiciones de insesgadez y varianza mínima y bajo ciertas condiciones, donde interviene el coeficiente de correlación entre los conglomerados de ambas ocasiones, el muestreo en dos ocasiones bajo un diseño de muestreo por conglomerados es más eficaz que el muestreo en dos ocasiones con un muestreo aleatorio simple.
