# NEWS for sure package


### Changes for version 0.2.0
* New function `surrogate` for returning the surrogate response values used in calculating the surrogate-based residuals. The surrogate response values can be useful for checking the proportionality assumption of fitted cumulative link models, among other things.
* Jittering (on both the probability scale and the response scale) is now available for fitted cumulative link models based on packages `MASS`, `ordinal`, `rms`, and `VGAM` [(#18)](https://github.com/AFIT-R/sure/issues/18).
* Added support for vector generalized additive models from the `VGAM` package (i.e., objects of class `"vgam"`).
* New data sets `df4` and `df5` for illustrating various uses of the surrogate residual for diagnostics an ordinal regression models.


### Changes for version 0.1.2
* Initial release.
