La importancia del espacio para minimizar el error de muestras representativas
Palabras clave:
regionalización, estratificación espacial, muestreo espacializadoResumen
En el presente trabajo se discute la importancia del espacio geográfico en el contexto de la generación de marcos muestrales de encuestas, poniendo en tensión la premisa estadística tradicional de la aleatoriedad e independencia de las observaciones. Para esto se analiza el aporte de la geografía cuantitativa en la generación de metodologías de regionalización que permitan de manera efectiva mejorar el error muestral de las encuestas, enfocados principalmente en las áreas urbanas, en presencia de variables de estratificación con autocorrelación espacial.
Finalmente se testea de forma empírica algoritmos de regionalización, utilizando datos censales, de manera de verificar si el nivel de error de las metodologías de muestreo espacializado son competitivas contra muestreos tradicionales de corte aleatorio y aleatorio bi-etápico, situación que es comprobada alcanzando rendimientos de hasta un 20% en la disminución de error contra metodologías tradicionales o en su defecto la disminución de hasta 100 casos con el mismo nivel de error.
