generate.bage_ssvd: Generate Random Age or Age-Sex Profiles

In bage: Bayesian Estimation and Forecasting of Age-Specific Rates

Generate Random Age or Age-Sex Profiles

Description

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,
  v = NULL,
  n_draw = 20,
  n_comp = NULL,
  indep = NULL,
  age_labels = NULL,
  ...
)

Arguments

x	An object of class "bage_ssvd".
v	Version of data to use.
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 the data contains a sex/gender variable. The default is to use independent SVDs. To obtain results for the total population when the data contains a sex/gender variable, set indep to NA.
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.

• HFD Fertility rates from the Human Fertility Database.

• LFP Labor forcce participation rates from the OECD.

See Also

• components() Components used by SVD prior.

• SVD() SVD prior for term involving age.

• SVD_AR1(), SVD_AR(), SVD_RW(), SVD_RW2() Dynamic SVD priors for terms involving age and time.

• poputils::age_labels() Generate age labels.

Examples

## females and males modeled independently
generate(HMD) 

## joint model for females and males
generate(HMD, indep = FALSE) 

## SVD for females and males combined
generate(HMD, indep = NA)

## specify age groups
labels <- poputils::age_labels(type = "lt", max = 60)
generate(HMD, age_labels = labels)
