Module phase 

Phase I/II framework for statistical process monitoring.

Phase I: Builds a monitoring chart from historical in-control data by splitting into tuning (for FPCA) and calibration (for control limits) sets.

Phase II: Monitors new observations against the established chart.

Both univariate and multivariate variants are provided.
