Life table" primarily refers to period life tables, as cohort life tables can only be constructed using data up to the current point, and distant projections for future mortality. Life tables can be constructed using projections of future mortality rates, but more often they are a snapshot of age-specific mortality rates in the recent past, and ...
Lexis diagram showing the cohort of 2003-born persons in green, and the year 2005 in red. In demography , a Lexis diagram (named after economist and social scientist Wilhelm Lexis ) is a two-dimensional diagram used to represent events (such as births or deaths) that occur to individuals belonging to different cohorts .
Actuarial notation is a shorthand method to allow actuaries to record mathematical formulas that deal with interest rates and life tables.. Traditional notation uses a halo system, where symbols are placed as superscript or subscript before or after the main letter.
The Ogden tables are a set of statistical tables and other information for use in court cases in the UK. Their purpose is to make it easier to calculate future losses in personal injury and fatal accident cases. The tables take into account life expectancy and provide a range of discount rates from -2.0% to 3.0% in steps
Survivorship curves can be constructed for a given cohort (a group of individuals of roughly the same age) based on a life table. There are three generalized types of survivorship curves: [ 1 ] Type I or convex curves are characterized by high age-specific survival probability in early and middle life, followed by a rapid decline in survival in ...
In a life table, we consider the probability of a person dying from age x to x + 1, called q x. In the continuous case, we could also consider the conditional probability of a person who has attained age ( x ) dying between ages x and x + Δx , which is
It is computed by subtracting the probable duration of bed disability and inability to perform major activities from the life expectancy. The data for calculation is obtained from population surveys and period life table. The Sullivan's index collects mortality and disability data separately, and this data is almost often readily available. The ...
The Lee–Carter model is a numerical algorithm used in mortality forecasting and life expectancy forecasting. [1] The input to the model is a matrix of age specific mortality rates ordered monotonically by time, usually with ages in columns and years in rows. The output is a forecasted matrix of mortality rates in the same format as the input.
