Bootstrap-Based Inference for Grouped Data

Abstract: RESUMEN: Los datos agrupados se refieren a variables continuas que se dividen en intervalos no necesariamente de la misma longitud para facilitar su interpretación. Contrario a lo que ocurre en datos no agrupados, la estimación de simples estadísticos de resumen como la media o la moda, o más complejos como un percentil o el coeficiente de variación, es una tarea difícil en datos agrupados. Cuando no se conoce la distribución de probabilidad que genera los datos, la inferencia en datos no agrupados se realiza … Show more

“…Rather, they prefer to release data such as household income, house prices, insurance losses, profits, and age in an interval format. The interval format can contain either grouped data [18] or symbolic data [1]. This work focuses on grouped data, where for a particular variable, only the intervals and the frequency of observations falling into each interval are known.…”
