1 What s New in Minitab 17 Jason Krasowitz Minitab Inc. ASQ NEQC 60 th Conference, Springfield, Massachusetts 1

2 Welcome to Minitab 17! Minitab 17 offers numerous new features and enhancements including improvements to: Assistant Regression and GLM DOE 2

3 Top The Enhancements Assistant 3

4 Making Data Analysis Even Easier Over the years, customers have told us: I don t know which tool to use The dialogs are too technical Minitab has too many options I need help interpreting my results 4

5 Graphs Control Charts Capability DOE ASSISTANT Regression MSA Hypothesis Tests Designed for Green/Black Belts, occasional users, and those who are new to statistics or Minitab 5

6 Assistant for DOE DOE easier than ever Most requested Assistant feature Screening designs 6-15 factors 2-5 factors Modeling 2 designs (x & x 2 ) 6

7 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: Plan and create experiments Analyze the data Conduct residuals analysis Find optimal settings 7

8 Improved Graphical Analysis Easier Dialogs + More Extensive Output 8

9 What value does it provide? Better dialogs e.g. shows categorical samples Diagnostic reports with guidance Report card with next steps 9

10 Assistant for Multiple Regression 10

11 What value does it provide? Regression is used everywhere Customers liked Minitab 16 Assistant, but only for 1X Easier for our users to: Find significant factors Conduct residuals analysis Identify outliers Find optimal settings 11

12 Top Regression Enhancements & GLM 12

13 Easily specify factors Automatic model selection Regression Binary Logistic Regression GLM More graphs Response optimizer 13

14 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 14

15 Graphs include Binary Fitted Line Plot 15

16 Design Top Enhancements of Experiments 16

17 Automatic model selection 17

18 Response Optimizer for General Factorial Designs (>2 levels) 18

19 Response Surface with Categorical X s 19

20 Box-Cox for Factorial and RS Non-hierarchical models Effects, main effects and interaction plots can display all terms, including terms removed from model Cube plots of fitted values available for reduced models Response optimizer: Constraints for Factorial and RS Doesn t require min/max value Provides CI and PI tables 20

21 Additional Features 21

22 Assistant enhancements throughout 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 2D space 22

23 Outlier Tests - Grubbs and Dixon s 23

24 Poisson Regression y = f (x) Model count data (Y), typically low counts/rare events Examples: number of machine failures or C-sections per time period Historical application In 1898, Ladislaus Bortkiewicz s investigation of the number of Prussian army soldiers killed by horse kicks 24

25 Equivalence Tests to determine if mean(s) are similar enough to be considered equivalent 25

26 Stability Studies Pharmaceuticals Determine shelf-life 26

27 One-Way ANOVA Stacked and unstacked all-in-one menu Welch s method For unequal variances First introduced in Minitab 16 Assistant Comparisons graphs Note: No Two-Way ANOVA menu 27

28 C 2 New name for Two-Way Table Raw or summarized data for 2-way tables Chi-Square Tests Chi-Square Test for Association Specify Session labels for 2-way tables Cross Tab and Chi-Square Raw or summarized/table data McNemar s Test for 2x2 paired proportions 28

29 Round date/time Updated graph style and symbols Updated worksheet font and column formula/model symbols, plus Missing indicator for text columns Minitab in Portuguese Plus English, French, Spanish, German, Simplified Chinese, Korean and Japanese (8 languages) 29

30 Additional Details to Features Note 30

31 Tooltips for all menus Graphs no longer editable in Word or PowerPoint EDA menu no longer displayed by default New hypothesis test dialogs and output symbols Unstacked data option for Test for Equal Variances, and multiple comparisons graph with new method replaces Bonferroni graph 2 Variances graphical output, Bonett s Correlation added Spearman s GLM > Results option to display coeffs for all factor levels Fisher s added to GLM Comparisons 31

32 DOE alpha switched to confidence level, from Graphs to Options Response optimizer displays composite desirability by default only when >1 Y Gage R&R default alpha for part*operator = 0.05 Control Charts default stdev Capability Rbar & Sbar default method for any charts that include R or S charts (Xbar by itself uses pooled) Overall statistics now provided 1 st Control charts default stdev change affects Sixpack 32

33 Exponential distribution option for T charts Tolerance Interval graph includes achieved confidence for nonparametric method Reliability default estimation method now maximum likelihood PSS for Equivalence Tests and Tolerance Intervals Balanced & General MANOVA combined into 1 dialog Manage Profiles includes DMAIC (Assistant) 33
