Density

density() computes the density matrix that accounts for the weighted proportions of the products connected to each good that the countries are exporting.

density(balassa_index, proximity_product)

Arguments

balassa_index

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

proximity_product

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

Value

A matrix.

Details

The current implementation follows (Hausmann et al. 2014) to measure the oppotunities implied by a country's position.
