A censored mixture model for modeling risk taking
share
Risk behavior can have substantial consequences for health, well-being, and functioning. Previous studies have shown an association between real-world risk behavior and risk behavior on experimental tasks, such as the Columbia Card Task, but their modeling is challenging for several reasons. First, many of the experimental risk tasks may end prematurely leading to censored observations. Second, certain outcome values can be more attractive than others. Third, a priori unknown groups of participants can react differently to certain risk-levels. Here, we propose the Censored Mixture Model (CMM), which models risk taking while handling censoring, experimental conditions, and attractiveness to certain outcomes.
