ci_geom_bod_intertemp: Intertemporal analysis for geometric mean quantity index numbers

Description

Intertemporal analysis for geometric mean quantity index numbers with Benefit-of-the-Doubt weights - see function ci_bod_constr.

Usage

ci_geom_bod_intertemp(x0,x1,indic_col,up_w,low_w,bench)

Arguments

x0

A data.frame containing simple indicators - time 0

x1

A data.frame containing simple indicators - time 1

indic_col

A numeric list indicating the positions of the simple indicators.

up_w

Weights upper bound.

low_w

Weights lower bound.

bench

Row number of the benchmark unit

Value

An object of class "CI". This is a list containing the following elements:

ci_geom_bod_intertemp_est

A matrix containing the Overall Change (period t1 vs t0), the Change Effect (period t1 vs t0), the Benchmark Effect (period t1 vs t0) and Weight Effect (period t1 vs t0).

ci_method

Method used; for this function ci_method="Intertemporal_effects_Geometric_BoD".
