¿Cómo Implementar un Modelo de Volatilidad Usando Lenguaje R?

Abstract

El modelado y pronóstico de series de tiempo financieras es una actividad de interés económico para los agentes del mercado. Las series de tiempo provenientes de ésta área a menudo presentan relaciones dinámicas complejas entre sus variables las cuales pueden ser capturadas mediante modelos de volatilidad. Estos pueden ser implementados en la mayoría de entornos de programación existentes. Sin embargo, la implementación de los modelos es compleja por no tener pautas para diseñar e implementar su código. Dado que R es un entorno de programación gratuito y estable, en este trabajo se proponen algunas pautas para diseñar e implementar el código de un modelo de volatilidad en R; como caso de ejemplo, se propone la creación del paquete Volatility que incluye el modelo de volatilidad GARCH y se mostrará su aplicabilidad al modelar la volatilidad de una serie de tiempo real.
