Making Data Analysis Even Easier

► Over the years, customers have told us:

“I don’t know which tool to use”

“Minitab has too many options”

“The dialogs are too

technical”

“I need help interpreting my results”

© 2013 Minitab, Inc.

Designed for Green/Black Belts, occasional users, and those

who are new to statistics or Minitab

Assistant for DOE

► DOE easier than ever► Most requested Assistant feature

2

6-15 factors

2-5 factors

© 2013 Minitab, Inc.

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

Assistant for Multiple Regression

© 2013 Minitab, Inc.

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

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

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

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:– Factorial allows for constraints– Doesn’t require min/max value– Only displays composite desirability for >1 X– Provides CI and PI tables
