Crate u_analytics 

u-analytics

Statistical process control (SPC), process capability analysis, Weibull reliability, and change-point detection.

This crate provides industrial quality analysis tools that are domain-agnostic — they operate on raw f64 data without knowledge of manufacturing, scheduling, or any specific consumer domain.

Modules

• spc — Control charts (X̄-R, X̄-S, I-MR, P, NP, C, U) with run rules
• capability — Process capability indices (Cp, Cpk, Pp, Ppk, Cpm)
• weibull — Weibull parameter estimation (MLE, MRR) and reliability analysis
• detection — Change-point detection (CUSUM, EWMA)
• smoothing — Time series smoothing (SES, Holt, Holt-Winters)

Design Philosophy

• Domain-agnostic: No manufacturing or process-specific types
• Numerical stability: Leverages u-numflow for stable statistics
• Research-backed: All algorithms reference academic literature
