poisson gamma distribution | poisson gamma distribution negative binomial In the probability density function of gamma distribution if we take alpha nearer to 50 we will get the nature of density function as Gamma distribution exponential familyĮven the shape parameter in gamma distribution we are increasing which is resulting in similarity of normal distribution normal curve, if we tend shape parameter alpha tends to infinity the gamma distribution will be more symmetric and normal but as alpha tends to infinity value of x in gamma distribution will tends to minus infinity which result in semi infinite support of gamma distribution infinite hence even gamma distribution becomes symmetric but not same with normal distribution. If we restrict the known value of α (alpha) this two parameter family will reduce to one parameter exponential familyĪnd for λ (lambda) Relationship between gamma and normal distribution The gamma distribution exponential family and it is two parameter exponential family which is largely and applicable family of distribution as most of real life problems can be modelled in the gamma distribution exponential family and the quick and useful calculation within the exponential family can be done easily, in the two parameter if we take probability density function as In this article we will discuss the special forms of gamma distributions and the relationships of gamma distribution with different continuous and discrete random variables also some estimation methods in sampling of population using gamma distribution is briefly discuss.
