Welcome to Minitab 17!

Minitab 17 offers numerous new features and enhancements including improvements to:

Assistant Regression and GLM DOE

October 22, 20142


Top EnhancementsThe Assistant

October 22, 20143


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”

October 22, 20144


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

who are new to statistics or Minitab

October 22, 20146


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

October 22, 20147


Improved Graphical AnalysisEasier Dialogs +

More Extensive Output

October 22, 20148



► Better dialogs – e.g. shows categorical samples

► Diagnostic reports with guidance

► Report card with next steps

October 22, 20149


Assistant for Multiple Regression

October 22, 201410



► 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

October 22, 201411

GLM

October 22, 201413



► 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

Response Optimizer for

General Factorial Designs (>2 levels)

October 22, 201418


Response Surface with Categorical X’s

October 22, 201419


► 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 tablesOctober 22, 2014

Additional FeaturesAdditional Features

October 22, 201421


► Assistant enhancements throughout

► 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

y = f (x)►Poisson Regression

October 22, 201424

enough to be considered equivalent

October 22, 201425
