A tiny Julia package which calculates weighted medians and means. Yep, that's it!
Installation:
julia> Pkg.add("WeightedStats")
Use:
julia> using WeightedStats
julia> data = [2, 0.6, 1.3, 0.3, 0.3, 1.7, 0.7, 1.7, 0.4];
julia> weights = [2, 2, 0, 1, 2, 2, 1, 6, 0];
julia> println(weighted_median(data, weights))
1.7
julia> println(weighted_mean(data, weights))
1.275
Boom!
