SurrogateRsq: Goodness-of-Fit Analysis for Categorical Data 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.
