This also applies to theF-distribution, where the incomplete Beta function enters the scene; see for instance the appendix in Hogg and Klugman (1984). The purpose of this paper is to derive an explicit formula for the first two moments of the Inverse Gaussian distribution, in the presence ...
The reciprocal of a random variable’s probability distribution. For example, The inverse gamma distribution is the reciprocal of the gamma distribution. Sampling up to a certain number of successes. See: Inverse sampling. Distributions where frequencies are reciprocal quantities (e.g. the factorial ...
In this paper, we studied the effect of square root transformation on the error component of the multiplicative error model whose distribution belongs to the generalized gamma family. The purpose of the study is to determine the effect o... J Ohakwe,AC Akpanta - 《Mathematical Theory & Model...

With the prior transformation formula, one could apply Bayesian imputation under the normal linear model with normal inverse-gamma priors. This holds for both the prior information about the distribution of the data (e.g. location and scale of variables) and the scientific model (e.g. ...
Using the formula proposed by Galton20and Moors21, one can get the numerical results for Skewness (Sk) and Kurtosis (Ku) by the help of quartiles from Eq. (11) as $$\begin{aligned} Sk=\dfrac{(K_{3}-2K_{2}+K_{1})}{(K_{3}-K_{1})} =\dfrac{(k_{(0.75)}-2k_{(0.5)}...

distribution during the inversion. Practically, this means two things. First, the data need to be in the range of permeability models that are in distribution. This means that there can not be too much noise neither can the observed data be the result of an out-of-distribution permeability....
