| dc.description.abstract | En este trabajo se propone emplear un modelo en el marco de teoría de respuesta al ítem a través de estimación Bayesiana, con el objetivo de medir el trazo latente relacionado con el perfil de riesgo de inversión de las personas naturales que participan en el mercado financiero Colombiano. Para obtener los datos necesarios, se encuestaron a 144 individuos por medio de un cuestionario inicial compuesto por 18 ítems, construido a partir de una investigación rigurosa sobre los métodos y tipos de cuestionarios que emplean las principales entidades financieras del país para medir el perfil de riesgo de sus clientes. Se estimó un modelo Generalized Partial Credit Model (GPCM) en el lenguaje estadístico Stan, presentando buen desempeño en términos de convergencia de las cadenas de markov y de bondad de ajuste evaluado por medio del criterio predictivo p-valor bayesiano para los ítem finales y el modelo global. | spa |
| dc.description.abstract | In this research we propose a model in the framework of item response theory through bayesian estimation, with the aim of measuring the latent trace related to the investment risk profile of natural persons participating in the Colombian financial market. For obtain the necessary data, 144 individuals were surveyed using an initial questionnaire made up of 18 items, constructed from rigorous research on the methods and types of questionnaires used by the country's main financial institutions to measure the risk profile of their clients. A Generalized Partial Credit Model was estimated in the statistical language Stan, showing good performance in terms of convergence of the markov chains and goodness of fit evaluated by means of the predictive bayesian p-value criterion for the finals items and the overall modell. | spa |
