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

Package 'bage'

Description

Bayesian estimation and forecasting of age-specific rates. Estimation uses TMB, and is fast.

Example workflow

1. Specify model using mod_pois()

2. Fit model using fit()

3. Extract results using augment()

4. Check model using replicate_data()

Functions

Specify model

• mod_pois() Specify a Poisson model

• mod_binom() Specify a binomial model

• mod_norm() Specify a normal model

• set_prior() Specify prior for main effect or interaction

• priors List of available priors for main effects or interactions

• set_disp() Specify prior for dispersion/variance

• set_var_age() Identify age variable in data

• set_var_sexgender() Identify sex or gender variable in data

• set_var_time() Identify time variable in data

Fit model

• fit() Derive posterior distribution

• is_fitted() See if model has been fitted

Extract results

• augment() Add cell-level estimates to data

• components() Hyper-parameters

• tidy() One-line summary

• set_n_draw() Specify number of prior or posterior draws

Forecast

• forecast() Use model to obtain estimates for future periods

Check model

• replicate_data() Compare real and simulated data

• report_sim() Simulation study of model

SVD-based modelling of age profiles

• components() Matrices and offsets from scaled SVD

• generate() Random profiles

• HFD Scaled SVD of fertility rates from Human Fertility Database

• HMD Scaled SVD of mortality rates from Human Mortality Database

• LFP Scaled SVD of labor force participation rates from OECD

Data

• isl_deaths Deaths in Iceland

• kor_births Births in South Korea

• nld_expenditure Health expenditure in the Netherlands

• nzl_divorces Divorces in New Zealand

• nzl_households One-person households in New Zealand

• nzl_injuries Fatal injuries in New Zealand

• swe_infant Infant mortality in Sweden

• usa_deaths Accidental deaths in the USA
