hbl_metrics {historicalborrowlong}

Borrowing metrics

Description

Calculate historical borrowing metrics using summary output from a fitted borrowing model and analogous summaries from the benchmark models.

Usage

hbl_metrics(borrow, pool, independent)

Arguments

borrow

A data frame returned by hbl_summary() for the hierarchical model.

pool

A data frame returned by hbl_summary() for the pooled model.

independent

A data frame returned by hbl_summary() for the independent model.

Value

A data frame with borrowing metrics.
