Complexity Measures

Description

complexity_measures() computes the Economic Complexity Index and the Product Complexity Index.

Usage

complexity_measures(
  balassa_index,
  method = "fitness",
  iterations = 20,
  extremality = 1
)

Arguments

balassa_index

(Type: dgCMatrix) the output from balassa_index()) or an equivalent arrangement.

method

(Type: character) one of these methods: fitness, reflections or eigenvalues. By default this is set to "fitness".

iterations

(Type: numeric) the number of iterations to use. By default this is set to 20.

extremality

(Type: numeric) the parameter to use in the fitness method. The other methods don't use this parameter. By default this is set to 1.

Details

The current implementation follows (Mariani et al. 2015) to obtain different alternatives that account for diversification in bipartite relations.

Value

A list of two named numeric vectors.
