Symbolic Calculus in Mathematical Statistics: A Review
Elvira Di Nardo
In the last ten years, the employment of symbolic methods has substantially extended both the theory and the applications of statistics and probability. This survey reviews the dev…
On a symbolic representation of non-central Wishart random matrices with applications
Elvira Di Nardo
By using a symbolic method, known in the literature as the classical umbral calculus, the trace of a non-central Wishart random matrix is represented as the convolution of the trac…
Natural statistics for spectral samples
E. Di Nardo, P. McCullagh, D. Senato
Spectral sampling is associated with the group of unitary transformations acting on matrices in much the same way that simple random sampling is associated with the symmetric group…
A new approach to Sheppard's corrections
Elvira Di Nardo
A very simple closed-form formula for Sheppard's corrections is recovered by means of the classical umbral calculus. By means of this symbolic method, a more general closed-form fo…
