Detailed Description

Fluctuation kernel using binomial distribution for use with bayesian_estimator.

The distribution of the observable \(X\) is given by the distribution

\[ f(X) = \frac{n!}{X!(n-X)!} p^{X}(1-p)^{n-X} \]

with mean value \(np\) and variance \(np(1-p)\).

Note: For this distribution, the reduced variance \(\sigma^2/\bar{X}<1\), greater than Poissonian fluctuations are not allowed.
