scoring_rules: Proper Scoring Rules for Categorical Data

In GLMMadaptive: Generalized Linear Mixed Models using Adaptive Gaussian Quadrature

Proper Scoring Rules for Categorical Data

Description

Calculates the logarithmic, quadratic/Brier and spherical based on a fitted mixed model for categorical data.

Usage

scoring_rules(object, newdata, newdata2 = NULL, max_count = 2000, 
    return_newdata = FALSE)

Arguments

object	an object inheriting from class "MixMod".
newdata	a data.frame based on which to estimate the random effect and calculate predictions. It should contain the response variable.
newdata2	a data.frame based on which to estimate the random effect and calculate predictions. It should contain the response variable.
max_count	numeric scalar denoting the maximum count up to which to calculate probabilities; this is relevant for count response data.
return_newdata	logical; if TRUE the values of the scoring rules are ruturned as extra columns of the newdata or newdata2 data.frame.

Value

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.
