%description
A system for creating the bilateral trade flow between a country pair
equal to zero. You provide the data, tell get_zerotradeflow() which
variables are of interest and it expands the base by creating the
bilateral zero trade flow. The bases on the flow of trade between
countries only report positive trade (greater than zero), however, for
some analyzes of gravitacional models, data on zero flow is also
necessary. Some examples for Gravity Model: Figueiredo and Loures (2016)
<doi:10.5935/0034-7140.20160015> and Yotov, Piermartini, Monteiro and
Larch <https://vi.unctad.org/tpa/web/docs/vol2/book.pdf>.
