COMPARACIÓN DE ALGUNOS R^2 COMO MEDIDAS DE BONDAD DE AJUSTE EN MODELOS LINEALES MIXTOS

Abstract

En este artículo se proponen dos estadísticos R^2 para evaluar la bondad de ajuste en modelos lineales mixtos con datos longitudinales. Se llevó a cabo un estudio de simulación para evaluar y comparar los estadísticos R^2 propuestos junto con otros estadísticos R^2 reportados en la literatura. Finalmente, se aplican los distintos R^2 a datos reales. Se llega a la conclusión que los estadísticos R^2 propuestos tiene una interpretación intuitiva, rango bien definido y son medidas que se pueden interpretar en un sentido absoluto sin hacer referencia a un modelo nulo. Sin embargo, el estudio de simulación evidencia que al igual que los otros estadísticos, los estadísticos R^2 propuestos, en algunas ocasiones, son incapaces de discriminar cuando las variables eliminadas del modelo son importantes

Keywords
