Análisis de duración mediante un modelo lineal generalizado semiparamétrico

Análisis de duración mediante un modelo lineal generalizado semiparamétrico

Abstract

Aitkin y Clayton (1980) proponen el análisis de modelos de duración mediante modelos lineales generalizados. En este trabajo extendemos esta metodología permitiendo que el efecto de alguna de las variables explicativas pueda no ser especificado. Así, el modelo propuesto es un modelo lineal generalizado semiparamétrico, con una componente paramétrica donde se especifica la forma funcional concreta del efecto de las variables explicativas sobre la duración, y una componente no paramétrica donde recogemos el efecto de una variable explicativa sin asumir forma funcional alguna. Desarrollaremos el proceso de estimación así como un procedimiento bootstrap para realizar inferencia. Como aplicación, analizaremos con la metodología propuesta el tiempo de supervivencia para una muestra de pacientes diagnosticados de SIDA.
