BACKGROUND Age patterns are a key dimension to compare migration between countries
and over time. Comparative metrics can be reliably computed only if data capture the …

Most denoising methods require that some smoothing parameters be set manually to
optimize their performance. Among these methods, a new filter based on nonlocal weighting …

This work examines the mortality characteristics of the population of Greece for the years
1961–2014. The time period considered is of special interest for the modern demographic …

We introduce the R package DBKGrad, conceived to facilitate the use of kernel smoothing in
graduating mortality rates. The package implements univariate and bivariate adaptive …

Parametric maximum likelihood (ML) estimators of probability density functions (pdfs) are
widely used today because they are efficient to compute and have several nice properties …

Modelling and forecasting mortality is a topic of crucial importance to actuaries and
demographers. However, forecasts from the majority of mortality projection models are …

Accurate forecasts of age-specific fertility rates are critical for government policy, planning
and decision making. With the availability of the Human Fertility Database (2011), the paper …

A topic of interest in demographic literature is the graduation of the age-specific fertility
pattern. A classical graduation technique extensively used by demographers is to fit …

Mortality data by age are known have a non linier pattern likes a bath-tub shape. There are
some parametric regression models developed to reveals the relationship between age and …

Some limit results on GM estimator of nonparametric regression models are obtained in this
article. In particular, the r-th moment consistency and asymptotic normality for the estimator …
