An Over and Underdispersed Biparametric Extension of the Waring Distribution

Mathematics, 2021
A new discrete distribution for count data called extended biparametric Waring (EBW) distribution is developed. Its name is related to the fact that, in a specific configuration of its parameters, it can be seen as a biparametric version of the ...

Beta-Geometric Regression for Modeling Count Data on First Antenatal Care Visit (ANC) with Application

Journal of Biostatistics and Epidemiology, 2023
Introduction: Although geometric distribution, which is a special case of Negative Binomial (NB) distribution, also belongs to the discrete family of distributions, little attention has been paid to modeling count data with the geometric distribution ...
