Researchers have introduced the zero-one censored transformed normal (ZOC-TN) model, designed for proportional outcomes that may have probability mass at the boundaries of 0 and 1. This model integrates a censored Gaussian variable with an affine-logit transformation for interior values, offering greater flexibility in density shapes compared to existing benchmark models. The ZOC-TN model can be extended to incorporate tree-boosting machine learning for nonlinearities and interactions, and it has been applied to loss given default modeling in U.S. residential mortgages, showing strong performance with a spatio-temporal frailty Gaussian process.
