A Gentle Introduction to Bayesian Hierarchical Linear Regression Models
Juan Sosa, Jeimy Aristizabal
Considering the flexibility and applicability of Bayesian modeling, in this work we revise the main characteristics of two hierarchical models in a regression setting. We study the…
Time-Varying Coefficient Model Estimation Through Radial Basis Functions
Juan Sosa, Lina Buitrago
In this paper we estimate the dynamic parameters of a time-varying coefficient model through radial kernel functions in the context of a longitudinal study. Our proposal is based o…
