proximity {economiccomplexity}R Documentation

Proximity

Description

proximity() computes two matrices that account for the similarity between pairs of countries and pairs of products.

Usage

proximity(balassa_index, compute = "both")

Arguments

balassa_index

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

compute

(Type: character) the proximity to compute. By default this is "both" (both proximity matrices) but it can also be "country" or "product".

Details

The current implementation follows (Hausmann et al. 2014) to obtain the likelihood that two products "p1" and "p2" are exported by the same country and, conversely, that two countries "c1" and "c2" export the same product.

Value

A list of two matrices.
