SurrogateRsq: Evaluating the Goodness of Fit using the Surrogate R-Squared
To assess and compare the models' goodness of fit, R-squared is one
of the most popular measures. For categorical data analysis, however, no universally
adopted R-squared measure can resemble the ordinary least square (OLS) R-squared for
linear models with continuous data. This package implement the surrogate R-squared
measure for categorical data analysis, which is proposed in the study of
Dungang Liu, Xiaorui Zhu, Brandon Greenwell,
and Zewei Lin (2022) <doi:10.1111/bmsp.12289>. It can generate a point or interval measure of the surrogate
R-squared. It can also provide a ranking measure of the percentage contribution of
each variable to the overall surrogate R-squared. This ranking assessment allows one to
check the importance of each variable in terms of their explained variance. This package can
be jointly used with other existing R packages for variable selection and model
diagnostics in the model-building process.
