Welcome to Minitab 17! Minitab 17 offers numerous new features and enhancements including improvements to: The Assistant Regression and GLM DOE And more… © 2013 Minitab, Inc.
Top Enhancements The Assistant © 2013 Minitab, Inc.
Making Data Analysis Even Easier ► Over the years, customers have told us: “The dialogs are too technical” “I don’t know which tool to use” “Minitab has too many options” © 2013 Minitab, Inc. “I need help interpreting my results”
Graphs Control Charts Capability ASSISTANT Regression DOE MSA Hypothesis Tests Designed for Green/Black Belts, occasional users, and those who are new to statistics or Minitab © 2013 Minitab, Inc.
Assistant for DOE ► DOE easier than ever ► Most requested Assistant feature Screening designs 2 -5 factors © 2013 Minitab, Inc. Modeling 2 designs (x & x 2) 6 -15 factors
What value does it provide? ► Customers are already using DOE in core Minitab ► However, users really struggle with DOE: • Choosing the appropriate design • Analyzing the data is not always straightforward ► Easier for our users to: • • © 2013 Minitab, Inc. Plan and create experiments Analyze the data Conduct residuals analysis Find optimal settings
Assistant for Multiple Regression © 2013 Minitab, Inc.
What value does it provide? ► Regression is used everywhere ► Customers liked Minitab 16 Assistant, but only for 1 X ► Easier for our users to: • • © 2013 Minitab, Inc. Find significant factors Conduct residuals analysis Identify outliers Find optimal settings
Improved Graphical Analysis Easier Dialogs + More Extensive Output © 2013 Minitab, Inc.
What value does it provide? ► Better dialogs – e. g. shows categorical samples ► Diagnostic reports with guidance ► Report card with next steps © 2013 Minitab, Inc.
Top Enhancements Regression & GLM © 2013 Minitab, Inc.
Easily specify factors Automatic model selection Regression Binary Logistic GLM More graphs © 2013 Minitab, Inc. Response optimizer
What value does it provide? ► CONSISTENCY across regression and GLM ► Better workflow (e. g. stepwise > model fitting), plus new model dialog and “view model” ► More statistical features: • Automatic model selection • Prediction • And more! ► More graphical features • Factorial, contour and surface plots plus response optimizer © 2013 Minitab, Inc.
Binary Fitted Line Plot + other graphs © 2013 Minitab, Inc.
Design of Experiments Top Enhancements © 2013 Minitab, Inc.
Automatic model selection © 2013 Minitab, Inc.
Response Optimizer for General Factorial Designs (>2 levels) © 2013 Minitab, Inc.
Response Surface with Categorical Factors © 2013 Minitab, Inc.
DOE dialog changes • Alpha moved from Graphs to Options, called “Confidence level” • Box-Cox for Factorial and RS • Effects, main effects and interaction plots display all terms, includes excluded terms • Cube plots of fitted values available for reduced models • Response optimizer changes: – – © 2013 Minitab, Inc. Factorial allows for constraints Doesn’t require min/max value Only displays composite desirability for >1 X Provides CI and PI tables
Additional Features © 2013 Minitab, Inc.
► Assistant • • • Stacked data option for 2 -sample tests Chi-Square Goodness-of-Fit up to 12 levels (from 6) Capability analysis for unequal subgroup sizes Before/after control charts, plus Laney charts And more… ► Bubble Plots • Graph multiple variables in a 2 D space © 2013 Minitab, Inc.
► Outlier Tests • Grubbs’ and Dixon’s ► Poisson Regression • Model count data (Y), typically low counts/rare events • Examples: number of machine failures, C-sections © 2013 Minitab, Inc.
Poisson Regression f (x) = y ► Practical application In 1898, Ladislaus Bortkiewicz’s investigation of the number of Prussian army soldiers killed by horse kicks ► Example Residents in rural Tanzania are being attacked by lions, frequently resulting in severe injury and death © 2013 Minitab, Inc.
Y Lunar Cycle Days Xs Above/Below Horizon © 2013 Minitab, Inc.
