Homogeneity Test of the First-Order Agreement Coefficient in a Stratified Design. [PDF]

open access: yesEntropy (Basel), 2023
Gwet’s first-order agreement coefficient (AC1) is widely used to assess the agreement between raters. This paper proposes several asymptotic statistics for a homogeneity test of stratified AC1 in large sample sizes.

Homogeneity Test for Multiple Semicontinuous Data with the Density Ratio Model

open access: yesMathematics, 2023
The density ratio model has been widely used in many research fields. To test the homogeneity of the model, the empirical likelihood ratio test (ELRT) has been shown to be valid. In this paper, we conduct a parametric test procedure.
