Complementary Romanovski-Routh polynomials and their zeros

Trends in Computational and Applied Mathematics
The efficacy of numerical methods like integral estimates via Gaussian quadrature formulas depends on the localization of the zeros of the associated family of orthogonal polynomials.

Predicting cervical cancer DNA methylation from genetic data using multivariate CMMP

Canadian Journal of Statistics, EarlyView.
Abstract Epigenetic modifications link the environment to gene expression and play a crucial role in tumour development. DNA methylation, in particular, is gaining attention in cancer research, including cervical cancer, the focus of this study.

Asymptotic formulae for linear equations [PDF]

Glasgow Mathematical Journal, 1972
Numerous formulae have been given which exhibit the asymptotic behaviour as t → ∞solutions ofwhere F(t) is essentially positive and Several of these results have been unified by a theorem of F. V. Atkinson [1]. It is the purpose of this paper to establish results, analogous to the theorem of Atkinson, for the third order equationand for the fourth ...

An observation‐driven state‐space model for claims size modelling

Canadian Journal of Statistics, EarlyView.
Abstract State‐space models are popular in econometrics. Recently, these models have gained some popularity in the actuarial literature. The best known state‐space models are of the Kalman‐filter type. These are called parameter‐driven because the observations do not impact the state‐space dynamics.

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

Canadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Realized Genome Sharing in Heritability Estimation Using Random Effects Models

G3: Genes, Genomes, Genetics, 2019
For heritability estimation using a two-component random effects model, we provided formulas for the limiting distribution of the maximum likelihood estimate.

Some Asymptotic Formulae for Gaussian Distributions

Journal of Multivariate Analysis, 1996
Asymptotic expansions (in powers of \(r^{-1}\) and \(\tau\)) for the expectation \[ Ef(r\varphi[\xi;r^{-1},\tau],\tau)g(\xi;r^{-1},\tau) \] are derived. Here \(\xi\) is a centered Gaussian vector with values in a separable real Hilbert space \(X\), functions \(g\) and \(\varphi:X\times [0,1]^2\to\mathbb{R}^d\), \(d\geq1\), are smooth in all of their ...

Optimal dividends for a NatCat insurer in the presence of a climate tipping point

Canadian Journal of Statistics, EarlyView.
Abstract We study optimal dividend strategies for an insurance company facing natural catastrophe claims, anticipating the arrival of a climate tipping point after which the claim intensity and/or the claim size distribution of the underlying risks deteriorates irreversibly.

Asymptotic approximations of complex order tangent, Tangent-Bernoulli and Tangent-Genocchi polynomials

Arab Journal of Basic and Applied Sciences
In this study, asymptotic formulas for complex order Tangent, Tangent-Bernoulli, and Tangent-Genocchi polynomials are obtained through the method of contour integration, strategically avoiding branch cuts in the process.
