🚀 Quickstart
import Pkg
Pkg.add("OnlineStats")
using OnlineStats
# Create several statistics
o = Series(Mean(), Variance(), Extrema())
# Update with single data point
fit!(o, 1.0)
# Iterate through and update with lots of data
fit!(o, randn(10^6))
# Get the values of the statistics
value(o) # (value(mean), value(variance), value(extrema))
