leontief_inverse_create: Create the inverse of a Leontief-matrix

Description

Create the Leontief inverse from the technology coefficient matrix.

Usage

leontief_inverse_create(technology_coefficients_matrix, digits = NULL)
leontieff_inverse_create(technology_coefficients_matrix, digits = NULL)

Arguments

technology_coefficients_matrix

A technology coefficient matrix created by the input_coefficient_matrix_create.

digits

An integer showing the precision of the technology matrix in digits. Default is NULL when no rounding is applied.

Details

The Leontief-inverse is $$L = (I-A)^-1$$ where B is the input coefficient matrix created by input_coefficient_matrix_create. For the similar inverse created from output coefficients, see the ghosh_inverse_create function.
