Variance
by axiomhq
High-precision one-pass variance and standard deviation computation library using Welford's method.
What it does
Variance provides an AI agent with specialized mathematical tools for performing stable, one-pass variance and standard deviation computations. It implements Welford's method and D.H.D. West's improvements, allowing the AI to process streams of data and merge multiple statistical sets without losing precision.
Tools
compute_variance: Calculate the variance and mean of a provided dataset in one pass.merge_statistics: Combine multiple sets of statistics into a single aggregated result.weighted_variance: Compute variance while accounting for weighted data values.
