We review two complementary mixture-based clustering approaches for modeling unobserved heterogeneity in an insurance portfolio: the generalized linear mixed cluster-weighted model (CWM) and mixture-based clustering for an ordered stereotype model (OSM). The latter is for modeling of ordinal...

This paper uses mortality fan charts to illustrate prospective future male mortality. These fan charts show both the … most likely path of male mortality and the bands of uncertainty surrounding that path. The fan charts are based on a model … of male mortality that is known to provide a good fit to UK mortality data. The fan charts suggest that there are clear …

For this, Dutch data on cause-of-death mortality and cause …-specific mortality data from 14 comparable European countries were used. We find that the inclusion of a common factor to a cause …

In the field of mortality, the Lee–Carter based approach can be considered the milestone to forecast mortality rates …–Carter model, the κ t parameter, describing the mortality trend over time, plays an important role about the future mortality … behavior. The traditional ARIMA process usually used to model κ t shows evident limitations to describe the future mortality …

Estimation of future mortality rates still plays a central role among life insurers in pricing their products and … managing longevity risk. In the literature on mortality modeling, a wide number of stochastic models have been proposed, most … of them forecasting future mortality rates by extrapolating one or more latent factors. The abundance of proposed models …

The first extracts …-parametric smoothing techniques to model mortality and thus has no explicit constraints placed on the model. We argue that from a … using Great Britain male mortality data from 1950–2016. We also conduct a robustness test to see how sensitive the forecasts …

Pension funds, which manage the financing of a large share of global retirement schemes, need to invest their assets in a diversified manner and over long durations while managing interest rate and longevity risks. In recent years, a new type of investment has emerged, that we call a longevity...

Predicting the evolution of mortality rates plays a central role for life insurance and pension funds. Standard single … decomposition of the mortality surface into a polynomial basis. Then, we show how regularization techniques and cross-validation can … be used to obtain a parsimonious and coherent predictive model for mortality forecasting. We analyze how COVID-19-type …
