Abstract
This paper develops a New Bivariate-Gamma Distribution (NBGD) and explores its mathematical and statistical properties such as marginal probability distributions, moments, product moment, covariance and correlation. The study further investigates the various special cases of the NBGD. The new distribution is more robust with additional parameters and flexible for modelling real datasets.
Keywords: Bivariate -distribution, \(\Gamma\)-distribution, marginal distributions, covariance, correlation
