%description
Implements the Ebrahim-Farrington goodness-of-fit test for logistic
regression models, particularly effective for sparse data and binary
outcomes. This test provides an improved alternative to the traditional
Hosmer-Lemeshow test by using a modified Pearson chi-square statistic with
data-dependent grouping. The test is based on Farrington (1996)
theoretical framework but simplified for practical implementation with
binary data. Includes functions for both the original Farrington test (for
grouped data) and the new Ebrahim-Farrington test (for binary data with
automatic grouping). For more details see Hosmer (1980)
<doi:10.1080/03610928008827941> and Farrington (1996)
<doi:10.1111/j.2517-6161.1996.tb02086.x>.
