🚀 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))
