NWA Quality Analyst®
NWA MvSPC™: Multivariate Analysis module
Overview of NWA MvSPC™
NWA and Infometrix have partnered to create a fully integrated solution for multivariate modeling and SPC charting that overcomes many of the barriers to the adoption of multivariate process monitoring and improvement techniques. NWA Quality Analyst’s new multivariate SPC module, NWA MvSPC™, combines with Infometrix Pirouette® to simplify the data-collection, model-building, and deployment process for off-line and real-time applications.
The combination of Quality Analyst’s connectivity and ease-of-use with Infometrix Pirouette’s industry-leading multivariate analysis capabilities provides a complete, integrated, multivariate modeling and SPC analytics solution.
Key Features
NWA MvSPC seamlessly integrates NWA Quality Analyst® and Infometrix Pirouette, unifying multivariate modeling and SPC charting and analysis.
Quality Analyst’s database connectivity provides access to any process or laboratory data source. The same data connections are used for model building and ongoing multivariate and univariate SPC analysis.
One-click access to contribution charts simplifies the interpretation of out-of-control points by listing variables by their relative contribution.
Real-time analysis is provided by NWA Quality Analytics Server™ using the same database connections and multivariate models, simplifying the transition from off-line to real-time multivariate SPC.
Fully integrated model building combines Quality Analyst’s exceptional database connectivity capabilities with Pirouette’s comprehensive multivariate modeling techniques.
Multivariate models are incorporated into the Quality Analyst Data Set definitions. These Data Sets can be connected to any industrial or laboratory database, and can include a combination of model and non-model variables. The same Data Set and database connection is used for model building and ongoing univariate and multivariate SPC charting and analysis.
Real-time multivariate SPC is provided by NWA Quality Analytics Server using the same Data Sets and model definitions created for off-line SPC charting and analysis.
NWA MvSPC requires models created by the current version of Infometrix Pirouette, which can be purchased from NWA or from Infometrix. Pirouette is only required to build the multivariate model.
Infometrix Pirouette is the leading chemometrics analytics package and provides a comprehensive selection of multivariate statistical analysis and visualization tools.
Contribution charts rank variables by their relative contribution to each SPC violation, helping identify the sources of variation and simplifying process improvement.
The model-building workflow is straightforward, using a point-and-click user interface and easy-to-understand forms to select variables and transfer information between Quality Analyst and Pirouette.
