Examples

distances <- french_cities_distances[1:10, 1:10] / 1000 ## convert to km
production <- log(french_cities$population[1:10])
attractiveness <- log(french_cities$area[1:10])
model <- static_blvim(distances, production, 1.5, 1 / 250, attractiveness)
production(model)
## the names of the production vector are set from the distance matrix
## we remove them for testing equality
all.equal(as.numeric(production(model)), production)
