Predictive Subgroup Logistic Regression for Classification with Unobserved Heterogeneity

Unobserved heterogeneity refers to the variation among subjects that is not accounted for by the observed features used in a model. Its presence poses a substantial challenge to statistical modeling. This study introduces the Predictive Subgroup Logistic Regression (PSLR) model, which extends the co...
