StMoMo: Stochastic Mortality Modeling in R
, 2018 In this paper we mirror the framework of generalized (non-)linear models to define the family of generalized age-period-cohort stochastic mortality models which encompasses the vast majority of stochastic mortality projection models proposed to date, including the well-known Lee-Carter and Cairns-Blake-Dowd models.

Muscle &Nerve, EarlyView.ABSTRACT Thymoma is the most common tumor of the anterior mediastinum. Approximately 20%–30% of patients with a thymoma develop myasthenia gravis (MG), and an additional one third may possess positive acetylcholine receptor (AChR) antibodies without MG.

Nordic Journal of Botany, EarlyView.Many habitat‐specialist plant species have been endangered by fragmentation or destruction of their habitats. Minuartia smejkalii is a serpentinophyte endemic to the Czech Republic. It is highly threatened by recent habitat destruction and fragmentation, calling for effective conservation measures.

Autocorrelation in Stochastic Models of Dutch Mortality Rates
MaRBLe, 2013 This paper studies different stochastic mortality models with respect to its underlying assumptions. The Lee-Carter model, the rank-p SVD approximation model, the Weighted Least Squares model and the Poisson Bilinear model are discussed and applied to a Dutch data set.

Stochastic portfolio specific mortality and the quantification of mortality basis risk
, 2009 In the last decade a vast literature on stochastic mortality models has been developed. However, these models are often not directly applicable to insurance portfolios because: (a) For insurers and pension funds it is more relevant to model mortality ...

A gravity model of mortality rates for two related populations
The mortality rate dynamics between two related but different-sized populations are modeled consistently using a new stochastic mortality model that we call the gravity model.

Point and interval forecasts of mortality rates and life expectancy: A comparison of ten principal component methods [PDF]
Using the age- and sex-specific data of 14 developed countries, we compare the point and interval forecast accuracy and bias of ten principal component methods for forecasting mortality rates and life expectancy.

Oikos, EarlyView.By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.
