tgr_summary: Summary of Technology Gap Ratios

In metafrontier: Analysis of Metafrontier Models for Efficiency and Productivity

Summary of Technology Gap Ratios

Description

Prints a summary table of TGR statistics by group. The underlying observation-level TGR values are the same as those returned by efficiencies(object, type = "tgr").

Usage

tgr_summary(object, ...)

Arguments

object	a fitted "metafrontier" object.
...	additional arguments (currently unused).

Value

A data frame with columns: Group, N, Mean, SD, Min, Q1, Median, Q3, Max.

Examples

sim <- simulate_metafrontier(n_groups = 2, n_per_group = 50,
                             seed = 42)
fit <- metafrontier(log_y ~ log_x1 + log_x2, data = sim$data,
                    group = "group", method = "sfa",
                    meta_type = "deterministic")
tgr_summary(fit)
