UnityWeb™ provides statistical process control (SPC) rules to monitor test performance. UnityWeb™ evaluates data points against the active SPC rules to determine whether to accept or reject the data. The software provides 17 different SPC rules, each of which can be set to reject, warn, or off.
Note: See "SPC Rules: Tabular Summary" for an overview of the available SPC rules.
Laboratories perform statistical analysis using tools such as OPSpecs Charts, critical-error graphs, and power function curves as described in numerous publications. However, using the optional Westgard Advisor™ online automates statistical analysis and suggests rules based on a selected performance goal, historical data, and Unity™ Interlaboratory Program consensus group information.
