In an assembly of macromolecules, a continuous distribution with the differential @[email protected] of the form: $f_{\text{w}}(x)\ \text{d}x = \frac{a^{b}\,+\,1}{\varGamma\left(b\,+\,1\right)}\ x^{b}\ \text{e}^{-a\ x}\ \text{d}x$ where $$x$$ is a parameter characterizing the @[email protected], such as @[email protected] or @[email protected], $$a$$ and $$b$$ are positive adjustable parameters, and ($$\mathit{\Gamma}\left(b+1\right)$$) is the gamma function of ($$b+1$$).
