Minitab 22 Features & Enhancements
Minitab Statistical Software Version 22.1.0 is available to customers who manage their Minitab subscription in the Minitab License Portal. This release includes new features and enhancements.
New Statistical Methods
Nonparametric Capability Analysis
Nonparametric Capability is in the Stat > Quality Tools > Capability Analysis menu.
User Benefit
Nonparametric Capability provides a robust solution to evaluate the capability of a process without any assumptions about the distribution of the data.
Summary
Capability analysis determines if a process can produce output that meets customer requirements. This determination depends on making the correct distribution assumptions or applying an appropriate transformation, like a Box-Cox or Johnson transformation. Nonparametric capability analysis provides a robust solution without any assumptions about the distribution of the data.
Automated Capability Analysis
Automated Capability is included in the Stat > Quality Tools > Capability Analysis menu.
User Benefit
When process data follow a nonnormal distribution, the search for an appropriate distribution or transformation becomes tedious and time-consuming. Automated Capability automatically selects an appropriate distribution, transformation, or nonparametric method to determine how well the process output meets customer specifications.
Summary
Automated Capability determines the appropriateness of the normal distribution and automatically presents alternative distribution fits or transformations. You can also use process knowledge to choose a different method from the automatic selection.
Evaluate Measurement Process (EMP Crossed)
Evaluate Measurement Process (EMP Crossed) is included in the Stat > Quality Tools > Gage Study menu.
User Benefit
When you assess the adequacy of a measurement system, one criterion is the ability of the measurement system to detect process changes. Dr. Wheeler’s Evaluating the Measurement Process (EMP) method considers this criterion and is a new alternative to the current Gage Study tools.
Summary
Evaluate Measurement Process (EMP Crossed) provides the tools to assess the process variation in a measurement system with crossed designs using the preferred Wheeler’s EMP criterion.
