What Is ‘Analytics’?
Analytics is the discovery and communication of meaningful patterns in data. It makes use of information technology, statistics and mathematical algorithms to develop knowledge, to quantify performance or to make predictions. It uses the insights gained from this process to recommend action or to guide decision making. Analytics is best thought of as a research procedure for decision making, not simply as isolated tools or steps in a process.

Important Considerations
• Big Data?
• Prediction versus Interpretation
• Statistics versus Machine Learning
![Page 9: Kevin Gray Festival of NewMR 2016](https://reader034.vdocuments.site/reader034/viewer/2022042722/58abb36b1a28ab04618b4b3d/html5/thumbnails/9.jpg)

‘Macro’ Categories
• Supervised methods are used when there is a dependent variable (‘label’)– e.g., regression, logistic regression
• Unsupervised methods are used when there is no dependent variable– e.g., cluster analysis, factor analysis
![Page 10: Kevin Gray Festival of NewMR 2016](https://reader034.vdocuments.site/reader034/viewer/2022042722/58abb36b1a28ab04618b4b3d/html5/thumbnails/10.jpg)

Popular Supervised Methods
• Generalized Linear Models (GLM) are a large family of statistical techniques
• Extremely versatile and can be used when dependent variable is:– Continuous (OLS regression)
– Categorical (binary logistic and multinomial logistic regression)
– Ordinal (ordered logistic regression)
– Count (Poisson regression)
– Repeated over time (longitudinal analysis)
– Clustered (e.g., departments within divisions of a company)

Popular Supervised Methods
• Methods widely-used in Data Science but less familiar to marketing researchers include:– K-nearest neighbors – Artificial Neural Networks (‘neural nets’)– Support Vector Machines – Boosting (e.g. AdaBoost)– Bagging (e.g. Random Forests)– MARS– GAM

Popular Unsupervised Methods
• K-means Cluster Analysis
• Agglomerative Hierarchical Clustering (‘AHC’)
• Partitioning Around Medoids (‘PAM’)
• Self-Organizing Maps (‘Kohonen networks’)
• Mixture Modelling and Latent Class
• Frequent Pattern Mining (e.g., Apriori, FP-Growth)
![Page 14: Kevin Gray Festival of NewMR 2016](https://reader034.vdocuments.site/reader034/viewer/2022042722/58abb36b1a28ab04618b4b3d/html5/thumbnails/14.jpg)

Structural Equation Modelling (SEM)
• SEM is arguably the most multitalented of the bunch...It is certainly the most general
• It unites GLM and Factor Analysis
• A Mixture Modelling variant (SEMM) adds Cluster Analysis
• It can also be used with longitudinal and clustered data
![Page 15: Kevin Gray Festival of NewMR 2016](https://reader034.vdocuments.site/reader034/viewer/2022042722/58abb36b1a28ab04618b4b3d/html5/thumbnails/15.jpg)

Time-Series Analysis
• A very large group of methods that originated in Engineering, Operations Research, Econometrics, Statistics and other disciplines
• Used when data have been collected at many points in time, (e.g., weekly sales)
• In MR used most often for sales forecasting and Marketing Mix Modelling (aka Market Response Modelling)
![Page 16: Kevin Gray Festival of NewMR 2016](https://reader034.vdocuments.site/reader034/viewer/2022042722/58abb36b1a28ab04618b4b3d/html5/thumbnails/16.jpg)

Time-To-Event Modelling
• Used for analyzing the expected time until one or more events happen
• Also known as Survival, Duration or Event History Analysis
• MR examples include:– What factors cause customer churn?– Predicting how long a customer will remain (‘survive’
as a) customer– Analysis of purchase behavior and website usage
![Page 18: Kevin Gray Festival of NewMR 2016](https://reader034.vdocuments.site/reader034/viewer/2022042722/58abb36b1a28ab04618b4b3d/html5/thumbnails/18.jpg)

Time-To-Event Modelling
• Quite complex…heavily used by Medical researchers and also by Economists, Engineers and in Operations Research
• Kaplan-Meier, Cox regression and parametric models are the main methods
• Modern variations can include a segmentation component rather than assuming all customers, patients, etc. are the same

Why Use Advanced Analytics?
• Advanced analytics adds value to data - it can help data speak to us! – For example, we can take respondent scale usage
patterns and background characteristics into account
– This provides us with a deeper and more accurate understanding of attitudes and behaviours and how they connect
![Page 20: Kevin Gray Festival of NewMR 2016](https://reader034.vdocuments.site/reader034/viewer/2022042722/58abb36b1a28ab04618b4b3d/html5/thumbnails/20.jpg)

Why Use Advanced Analytics?
• In any kind of research totals and crosstabs only show us the surface - they’re just the first steps in exploratory data analysis
• Moreover, running lots of crosstabs to find something interesting increases the risk of fluke ‘findings’...and clients can make bad decisions based these chance results!
![Page 21: Kevin Gray Festival of NewMR 2016](https://reader034.vdocuments.site/reader034/viewer/2022042722/58abb36b1a28ab04618b4b3d/html5/thumbnails/21.jpg)

Why Use Advanced Analytics?
• Looking at variables two-at-a-time can also be very misleading– older consumers may seem to be heavier users of
a particular category but…
– after taking gender, income and other characteristics into account, we may find that category usage actually declines with age!

Key Points
• What I’ve just shown are only some of the tools a Marketing Scientist may wish to include in their toolbox
• More than the tools, though, it is how they are used that’s most important
• Making advanced analytics work involves much more than math and programming
• You need to put the patient before the cure!

Future Directions
• IoT, Artificial Intelligence, Quantum Computing and unforeseen innovations will likely have a profound impact on our lives in the future
• This means they will also impact MR and analytics!
• Some kinds of analytics will be largely automated in the not-so-distant future, but human judgement will remain essential
• Further ahead, Marketing and MR may be extensively automated...but in that sort of world will they still be necessary?
