Detailed Description

Collects statistics (min,max,mean,stddev,etc) on floating-point data.

Collects datapoints incrementally and keeps statistics in a constant-sized structure.

There is a risk of numerical overflow and precision errors in the stddev and variance methods, when collecting many large values.

Print prints a concise, human-readable representation. Load and Save can be used for loading/saving to disk.
