We also have the following relationship between the gamma and the beta function: B(z,w)=Γ(z)Γ(w)Γ(z+w).C. ApplicationsC.1 Integral FormulasLet k1,⋯,kn be nonngeative even integers. Note that the integral ∫Rnx1k1⋯xnkne−|x|2dx=∏j=1n∫−∞+∞xjkje−xj2dxj=∏j...
Three definitions for the q-gamma function are obtained and the q-deformed duplication and multiplication formulas are proven. The q-beta function is defined and its useful properties are derived.doi:10.1063/1.530852CHUNG, WSKANG, HJJOURNAL OF MATHEMATICAL PHYSICS...

There are no closed formulas for solving these equations, so numerical methods are required. 3. Numerical Optimization for Solving the Score Equations In this section we are interested in proposing numerical methods for solving the score equations of the MLEs of the BP parameters. We will consider...
The optimality conditions dL/dα=0 and dL/dβ=0 must be solved numerically and iteratively because the parameters appear in the logarithm of the gamma function. In comparison to a mixture of Gaussians where analytical formulas exist for the ML estimators, this is inconvenient, but the main pr...
For any a∈(0,∞), we prove the strict concavity of the functionηa(t):=∑m=0∞(−1)m(am+1)t on (0,∞), and provide fast computations of their derivatives on (0,∞). We give short proofs mainly based on differentiation formulas concerning the gamma process. In particular, our...
