The moment generating function has its moments

Journal of Statistical Planning and Inference, 1986
For positive random variables all real moments of positive degree are obtained from the moment generating function. In case of moments of negative degree some integrability conditions on the moment generating function are required. Some generalizations and applications are discussed.

On Minimal-Moment Generating Functions

Extremes, 2002
For a distribution function \(F\) on \(R_+\) a minimal-moment generation function is defined as \(\varphi(z)=\sum_{k\geq 1}z^{k-1}m_k\), where \(m_k=\mathbf{E}[\min_{1\leq j\leq k} X_j]\), \(X_j\) are i.i.d. with d.f. \(F\). It is shown that under mild conditions \[ F^{-1}\left(1-{1\over \omega+\varepsilon}\right)- F^{-1}\left(1-{1\over \omega ...

Moment Generating Functions and Central Moments

2018
This section deals with the moment generating functions (m.g.f.) up to sixth order of some discretely defined operators. We mention the m.g.f. and express them in expanded form to obtain moments, which are important in the theory of approximation relevant to problems of convergence.

Laguerre moments and generalized functions

Journal of Physics A: Mathematical and General, 2002
In the paper the link between the moments of the Laguerre polynomials or Laguerre moments and the generalized functions (as the Dirac delta-function and its derivatives) is explored. Several interesting relations are presented. A useful application is related to a procedure for calculating mean values in quantum optics making use of the so-called quasi-

Orthogonal Polynomials through Moment Generating Functionals

SIAM Journal on Mathematical Analysis, 1978
It is shown that if the linear functional w generates moments $\{ \mu _i \} _{i = 0}^\infty $ through the formula $\mu _i = \langle {w,x^i } \rangle $, $i = 0,1, \cdots $, then the Chebyshev polyno...

Generalized moment function and conformal transform

SPIE Proceedings, 2002
We propose a new class of generalized moment functions (GMFs) that scan the object with different probing functions. Using the GMF, it is possible to extract a unique geometric point within the object, called the generalized centroid (G-centroid). We can obtain a set of discrete G-centroids from the same object by using different GMFs.

Estimation of the Moment Generating Function

Communications in Statistics - Simulation and Computation, 1989
A number of statistical problems use the moment generating function (mgf) for purposes other than determining the moments of a distribution. If the distribution is not completely specified, then the mgf must be estimated from available data. The empirical mgf makes no assumptions concerning the underlying distribution except for the existence of the ...

Moment Generating Functions and Moments of Linear Positive Operators

2018
In the theory of approximation, moments play an important role in order to study the convergence of sequence of linear positive operators. Several new operators have been discussed in the past decade and their moments have been obtained by direct computation or by attaining the recurrence relation to get the higher moments.
