Calculates the logarithmic, quadratic/Brier and spherical based on a fitted mixed model for categorical data.
scoring_rules(object, newdata, newdata2 = NULL, max_count = 2000,
return_newdata = FALSE)
A data.frame with (extra) columns the values of the logarithmic, quadratic and spherical
scoring rules calculated based on the fitted model and the observed responses in
newdata
or newdata2
.
an object inheriting from class "MixMod"
.
a data.frame based on which to estimate the random effect and calculate predictions. It should contain the response variable.
a data.frame based on which to estimate the random effect and calculate predictions. It should contain the response variable.
numeric scalar denoting the maximum count up to which to calculate probabilities; this is relevant for count response data.
logical; if TRUE
the values of the scoring rules are
ruturned as extra columns of the newdata
or newdata2
data.frame.
