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).
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.
