assessor 1.3.1

CRAN release: 2026-04-20

• dpit() now rejects non-Tobit VGAM::vglm objects and non-constant-scale VGAM Tobit fits with informative errors.
• dpit_2pm() now requires exactly one model or supplied-probability input for each component and uses one common calculation path.
• Corrected the ord_curve() axis documentation and threshold label, and clarified the plotting documentation for ord_curve() and quasi_plot().
• dpit_ordi() now respects the ordering supplied in level and validates the fitted category-probability matrix.
• Corrected the zero-inflated negative-binomial bandwidth calculation to use the negative-binomial CDF.
• Goodness-of-fit bootstrap refits now preserve offsets for binomial, Poisson, and negative-binomial regression models.
• gof_disc() now requires B to be a positive integer.
• Fixed an error where scale = "uniform" did not produce a uniformly scaled QQ plot.
• Fixed the negative-binomial goodness-of-fit bootstrap so that each replicate is refitted using the simulated response.
• dpit(), dpit_2pm(), and the distribution-specific calculators for binary, Poisson, negative binomial, ordinal, zero-inflated, Tobit, and Tweedie outcomes now return dpit objects. Use residuals() to extract values, summary() to summarize them, and plot() to draw QQ plots. The scale argument is now supplied to residuals(), summary(), or plot(), and graphical arguments are supplied to plot().
• The print() and summary() methods now label the number of residuals as the sample size.

assessor 1.3.0

CRAN release: 2026-03-22

Breaking changes

• Renamed all functions with prefix resid_* to dpit_*.
• Unified resid_disc(), resid_zeroinfl(), and resid_semiconti() into a single S3 generic function dpit().
• Renamed resid_quasi() to quasi_plot().

New features

• Added dpit_2pm() (formerly resid_2pm()).
• Introduced direct DPIT computation functions:
  • dpit_bin()
  • dpit_pois()
  • dpit_nb()
  • dpit_ordi()
  • dpit_znb()
  • dpit_zpois()
  • dpit_tobit()
  • dpit_tweedie()
• Added gof_disc(), an S3-based goodness-of-fit testing function for discrete outcome regression models.
• Updated quasi_plot() to an S3-based interface.

assessor 1.2.0

• Add bballHR data set which is used as an example for assessing a discrete outcome regression.

assessor 1.1.0

CRAN release: 2024-04-03
