Generate Random Age or Age-Sex Profiles

Generate random age or age-sex profiles from an object of class "bage_ssvd". An object of class "bage_ssvd" holds results from an SVD decomposition of demographic data.

Usage

# S3 method for class 'bage_ssvd'
generate(x, n_draw = 20, n_comp = NULL, indep = NULL, age_labels = NULL, ...)

Arguments

x

An object of class "bage_ssvd".

n_draw

Number of random draws to generate.

n_comp

The number of components. The default is half the total number of components of object.

indep

Whether to use independent or joint SVDs for each sex/gender. If no value is supplied, an SVD with no sex/gender dimension is used. Note that the default is different from SVD().

age_labels

Age labels for the desired age or age-sex profile. If no labels are supplied, the most detailed profile available is used.

...

Unused. Included for generic consistency only.

Value

A tibble

Scaled SVDs of demographic databases in bage

• HMD Mortality rates from the Human Mortality Database.

• LFP Labor forcce participation rates from the OECD.
