The STATISTICA PI Connector is an optional STATISTICA add-on component that allows for direct integration to data stored in the PI data historian. The STATISTICA PI Connector utilizes the PI user access control and security model, allows for interactive browsing of tags, and takes advantages of dedicated PI functionality for interpolation and snapshot data. STATISTICA integrated with the PI system is being used for streamlined and automated analyses for applications such as Process Analytical Technology (PAT) in FDA-regulated industries, Advanced Process Control (APC) systems in Chemical and Petrochemical industries, and advisory systems for process optimization and compliance in the Energy Utility industry.

This module provides options to simplify and facilitate access to, aggregation, and alignment of data from multiple databases, when some of the databases contain process data (such as from PI or similar databases), while others contain "static" data (e.g., from Oracle or MS SQL Server). Provides for ad-hoc querying and aligning of data, for subsequent analyses such as ad-hoc charting etc. of data describing a specific time interval.
Detailed Information
Variance Estimation and Precision (VEPAC) is a comprehensive set of techniques for analyzing data from experiments that include both fixed and random effects using REML (Restricted Maximum Likelihood Estimation). With VEPAC, users can obtain estimates of variance components and use them to make precision statements while at the same time comparing fixed effects in the presence of multiple sources of variation.
VEPAC includes the following:
- Variability plots
- Multiple plot layouts to allow direct comparison of multiple dependent variables
- Expected mean squares and variance components with confidence intervals
- Flexible handling of multiple dependent variables: analyze several variables with the same or different designs at once
- Graph displays of variance components
