Evaluating the performance of the lee-carter method for forecasting mortality [PDF]
Demography, 2001 Abstract Lee and Carter (LC) published a new statistical method for forecasting mortality in 1992. This paper examines its actual and hypothetical forecast errors, and compares them with Social Security forecast errors. Hypothetical historical projections suggest that LC tended to underproject gains, but by less than did Social ...

Predicting Human Mortality: Quantitative Evaluation of Four Stochastic Models
Risks, 2016 In this paper, we quantitatively compare the forecasts from four different mortality models. We consider one discrete-time model proposed by Lee and Carter (1992) and three continuous-time models: the Wills and Sherris (2011) model, the Feller process ...

Prediction of life expectancy using the Lee-Carter model [PDF]
, 2013 The ageing of the population is a problem of many European countries including the Czech Republic. This problem is related to two main factors, the increase of life expectancy and the decline of birth rate.

Improving mortality forecasting using a hybrid of Lee–Carter and stacking ensemble model
Bulletin of the National Research Centre, 2023 Background Mortality forecasting is a critical component in various fields, including public health, insurance, and pension planning, where accurate predictions are essential for informed decision-making.

Advanced Science, EarlyView.Mechanical cues, including ECM stiffness, stretch, compression, shear stress, and traction forces, remodel trafficking across the secretory pathway, from the ER and Golgi to endolysosomal compartments and the plasma membrane. The resulting secretome reshapes ECM composition and tissue mechanics, establishing feedback loops that support homeostasis or ...

Mortality modelling with arrival of additional year of mortality data: Calibration and forecasting [PDF]
Demographic ResearchBACKGROUND: For commonly used mortality models, the existing estimates change with the recalibration of new data. This issue is also known as the lack of the new-data-invariant property.

American Journal of Agricultural Economics, EarlyView.Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

Sociodemographic Factors Associated with Hours Worked by Primary Carers in Australia
Australian Journal of Social Issues, EarlyView.ABSTRACT Primary caregivers constitute a major unpaid workforce in Australia. The aim of this study was to determine the sociodemographic factors that are associated with carer workloads. Multinomial logistic regression modelling was applied to the nation‐wide Australian Government survey.

Deterministic and stochastic trends in the Lee–Carter mortality model [PDF]
Applied Economics Letters, 2015 The Lee and Carter (1992) model assumes that the deterministic and stochastic time series dynamics load with identical weights when describing the development of age-specific mortality rates. Effectively this means that the main characteristics of the model simplify to a random walk model with age-specific drift components.
