assessor: The goal of assessor is to provide assessment tools for regression models with discrete and semicontinuous outcomes proposed in Yang (2024) and Yang(2024). It calculates the double probability integral transform (DPIT) residuals, constructs QQ plots of residuals and the ordered curve for assessing mean structures.
