extract {tipsae}

Extract Posterior Summaries of Target Parameters

Description

The extract() function provides the posterior summaries of target parameters, including model-based estimates, and possibly benchmarked estimates, related to a fitted small area model.

Usage

extract(x)

Arguments

x

An object of class summary_fitsae or benchmark_fitsae.

Value

An object of class estimates_fitsae, being a list of two data frames, distinguishing between ⁠$in_sample⁠ and ⁠$out_of_sample⁠ areas, which gathers domains name, direct and HB estimates, as well as posterior summaries of target parameters. When the input is a benchmark_fitsae object, benchmarked estimates are also included.

See Also

summary.fitsae and benchmark to produce the input object.

Examples

library(tipsae)

# loading toy dataset
data("emilia_cs")

# fitting a model
fit_beta <- fit_sae(formula_fixed = hcr ~ x, data = emilia_cs, domains = "id",
                    type_disp = "var", disp_direct = "vars", domain_size = "n",
                    # MCMC setting to obtain a fast example. Remove next line for reliable results.
                    chains = 1, iter = 150, seed = 0)

# check model diagnostics
summ_beta <- summary(fit_beta)

# extract model estimates
HB_estimates <- extract(summ_beta)
head(HB_estimates)
