Explanation A binomial distribution depends much more on the number of trials or observations done. At the same time, each trial defines its own probability of outcome value or, in other words. A binomial random
Using these identities, as well as a few simple mathematical tricks, we derived the binomial distribution mean and variance formulas. In the last two sections below, I’m going to give a summary of these derivations. I know there was a lot of mathematical expression manipulation, some of whic...
The mean value of this simple experiment is: np = 20 × 0.5 = 10. We can say that on average if we repeat the experiment many times, we should expect heads to appear ten times. The variance of this binomial distribution is equal to np(1-p) = 20 × 0.5 × (1-0.5) = 5. Take...
, facts that follow from the simple ex- pression for the ratio of successive terms: <5.1> b n (k) b n (k −1) = (n −k +1) p kq for k = 1, 2, . . . , n. The plots on the left-hand side of the next display, for the Bin(n, 0.4) distribution with n = 20,...
The nega- tive binomial distribution can be expressed as a gamma mixture of Poisson distribution [41]: yi ~ Poisson(yi|μiεi) and εi ~ Gamma(θ, θ). It can be derived that E(yi) = μi, Zhang et al. BMC Bioinformatics (2017) 18:4 Page 3 of 10 Table 1 Microbiome Data ...

The normal distribution of dependent variables is one of the basic assumptions of traditional linear regression models; however, this hypothesis is usually not met in practice. For example, when the number of crimes was adopted as the dependent variable, the distribution no longer presented as a ...
