ENBIS-19 Pre-Conference Event: Joint ECAS-ENBIS 1-Day Summer Course

1 September 2019; 09:30 – 18:30

This 1-day course is a joint initiative from ENBIS and ECAS (ecas.fenstats.eu), which provides courses since 1987 in special areas of statistics both for researchers and teachers for universities and professionals in the industry.

The 1-day course is organised under the umbrella of the ENBIS-19 conference in Budapest. You can find more information about the conference here.

General aim of the course

Main puropose of this tutorial is to provide an introduction to the most known new product growth models (also called innovation diffusion models), used to describe and forecast the evolution in time of sales of new products. In most cases, commercial products are characterized by a finite life cycle, which follows a nonlinear path, namely birth, growth, maturity, and decline. In this context, traditional time series framework such as ARIMA models do not prove a satisfactory choice. Quantitative marketing has played a central role in the development of new product diffusion models. The statistical techniques involved in model estimation combine time series analysis with nonlinear regression techniques.

The key objectives of the course are:

  • to describe the main mathematical features of the models, illustrating the meaning of the parameters from the marketing point of view;
  • to present and discuss the statistical aspects involved in model estimation and selection;
  • to show and discuss forecasting and explanatory ability of the proposed models with real-data applications in several industrial and commercial sectors;
  • to propose some ideas for future achievements in research and commercial practice.

 

Highlights

  • New product forecasting: marketing problems and quantitative models.
  • New product life cycle as an empirical generalization: the Bass model.
  • Accounting for marketing mix actions: the Generalized Bass model.
  • Accounting for the strength of word-of-mouth, seasonality and competition: some advanced models.
  • Statistical inference for nonlinear models.
  • Forecasting for new product growth models.
  • Model selection and evaluation.

Workshop overview

Judea Pearl, the 2011 Turing Award winner who developed Bayesian networks and causality networks, recently published a bestselling book: The Book of Why. In that book he calls for a “causality revolution”. Causality has been treated by statisticians for many years, since the work of R. A. Fisher at Rothamsted agricultural station on designed experiments. The gold standard for determining causality has been the randomized controlled trial (RCT). A general framework for handling causality has been the Neyman-Rubin potential outcomes approach and the propensity score methods developed by Donald Rubin. This workshop will review basic tools for identifying causality variables, such as the fishbone diagram, present the versatile Bayesian network tool, discuss the critical role of randomization in designed experiments and introduce the methods proposed by Pearl and Rubin to assess causality relationships. Applications of these methods to personalized medicine, condition-based maintenance (CBM) and Industry 4.0 will also be discussed.

Workshop outline:

  1. Background on causality in science and statistics
  2. Fishbone cause and effect diagrams
  3. Bayesian networks
  4. Randomization in experimental designs
  5. Propensity scores in observational data
  6. Counterfactuals and do calculus
  7. Personalized medicine, condition-based maintenance and Industry 4.0
  8. Future research areas
