%description
Calculates commonly used indicators for empirical international trade
analysis from user-supplied data. Measures include trade openness,
bilateral export and import intensity, the Herfindahl-Hirschman
concentration index, normalized and entropy-based diversification,
structural diversification relative to a benchmark, export similarity,
trade complementarity, revealed comparative advantage, and intra-industry
trade. Functions are vectorized where appropriate, validate economically
meaningful inputs, and require no external data service. The definition of
trade openness follows the World Bank indicator metadata
<https://data.worldbank.org/indicator/NE.TRD.GNFS.ZS>. Methodological
background for several trade indicators is provided by the World Bank's
World Integrated Trade Solution
<https://wits.worldbank.org/wits/wits/witshelp/Content/Utilities/e1.trade_indicators.htm>
and the World Trade Organization (2012, ISBN:9789287038128).
