| pgmt | Der Praktikerguide für mulitvariate Techniken | 14 hours | The introduction of the digital computer, and now the widespread availability of computer packages, has opened up a hitherto difficult area of statistics; multivariate analysis. Previously the formidable computing effort associated with these procedures presented a real barrier. That barrier has now disappeared and the analyst can therefore concentrate on an appreciation and an interpretation of the findings. Multivariate Analysis of Variance (MANOVA) Whereas the Analysis of Variance technique (ANOVA) investigates possible systematic differences between prescribes groups of individuals on a single variable, the technique of Multivariate Analysis of Variance is simply an extension of that procedure to numerous variates viewed collectively. These variates could be distinct in nature; for example Height, Weight etc, or repeated measures of a single variate over time or over space. When the variates are repeated measures over time or space, the analyses may often be reduced to a succession of univariate analyses, with easier interpretation. This procedure is often referred to as Repeated Measure Analysis. Principal Component Analysis If only two variates are recorded for a number of individuals, the data may conveniently be represented on a two-dimensional plot. If there are ‘p’ variates then one could imagine a plot of the data in ‘p’ dimensional space. The technique of Principal Component Analysis corresponds to a rotation of the axes so that the maximum amounts of variation are progressively represented along the new axes. It has been described as …….‘peering into multidimensional space, from every conceivable angle, and selecting as the viewing angle that which contains the maximum amount of variation’ The aim therefore is a reduction of the dimensionality of multivariate data. If for example a very high percentage (say 90%) of the variability is contained in the first two principal components, a plot of these components would be a virtually complete pictorial representation of the variability. Discriminant Analysis Suppose that several variates are observed on individuals from two identified groups. The technique of discriminant analysis involves calculating that linear function of the variates that best separates out the groups. The linear function may therefore be used to identify group membership simply from the pattern of variates. Various methods are available to estimate the success in general of this identification procedure. Canonical Variate Analysis Canonical Variate Analysis is in essence an extension of Discriminant Analysis to accommodate the situation where there are more than two groups of individuals. Cluster Analysis Cluster Analysis as the name suggests involves identifying groupings (or clusters) of individuals in multidimensional space. Since here there is no ‘a priori’ grouping of individuals, the identification of so called clusters is a subjective process subject to various assumptions. Most computer packages offer several clustering procedures that may often give differing results. However the pictorial representation of the so called ‘clusters’, in diagrams called dendrograms, provides a very useful diagnostic. Factor Analysis If ‘p’ variates are observed on each of ‘n’ individuals, the technique of factor analysis attempts to identify say ‘r’ (< p) so called factors which determine to a large extent the variate values. The implicit assumption here therefore is that the entire array of ‘p’ variates is controlled by ‘r’ factors. For example the ‘p’ variates could represent the performance of students in numerous examination subjects, and we wish to determine whether a few attributes such as numerical ability, linguistic ability could account for much of the variability. The difficulties here stem from the fact that the so-called factors are not directly observable, and indeed may not really exist. Factor analysis has been viewed very suspiciously over the years, because of the measure of speculation involved in the identification of factors. One popular numerical procedure starts with the rotation of axes using principal components (described above) followed by a rotation of the factors identified. |

| mrkanar | Marketinganalytik mit R | 21 hours | Audience: Business owners (marketing managers, product managers, customer base managers) and their teams; customer insights professionals. Overview: The course follows the customer life cycle from acquiring new customers, managing the existing customers for profitability, retaining good customers, and finally understanding which customers are leaving us and why. We will be working with real (if anonymous) data from a variety of industries including telecommunications, insurance, media, and high tech. Format: Instructor-led training over the course of five half-day sessions with in-class exercises as well as homework. It can be delivered as a classroom or distance (online) course. Trainer: The Instructor has gained 19 years experience in customer insights and customer relationship management after originally graduating in experimental particle physics and working at the CERN laboratory. He has worked with large corporations across Europe and North America to transform the way they look at their customers and derive value from data, and has held interim management roles at leading Dutch and Irish mobile phone operators building their Insights and Customer Base Management teams. He is one of the founders of The PCA Group, which helps large corporations in Europe and South America transform their approach to marketing, and of CYBAEA, which provides analytics-as-a-service across the globe with a strong focus on commercial results. His teaching style focuses on practical example and emphasizes results over theoretical sophistication: his courses are for practitioners who need to deliver value to their organizations and while he covers just enough theory to make sure his students are on a firm footing his teaching is not geared to more theoretical students. Expect much hands-on work and very few formula. Part 1: Inflow - acquiring new customers Our focus is direct marketing so we will not look at advertising campaigns but instead focus on understanding marketing campaigns (e.g. direct mail). This is the foundation for almost everything else in the course. We look at measuring and improving campaign effectiveness. including: The importance of test and control groups. Universal control group. Techniques: Lift curves, AUC Return on investment. Optimizing marketing spend. Part 2: Base Management: managing existing customers Considering the cost of acquiring new customers for many businesses there are probably few assets more valuable than their existing customer base, though few think of it in this way. Topics include: 1. Cross-selling and up-selling: Offering the right product or service to the customer at the right time. Techniques: RFM models. Multinomial regression. b. Value of lifetime purchases. 2. Customer segmentation: Understanding the types of customers that you have. Classification models using first simple decision trees, and then random forests and other, newer techniques. Part 3: Retention: Keeping your good customers Understanding which customers are likely to leave and what you can do about it is key to profitability in many industries, especially where there are repeat purchases or subscriptions. We look at propensity to churn models, including Logistic regression: glm (package stats) and newer techniques (especially gbm as a general tool) Tuning models (caret) and introduction to ensemble models. Part 4: Outflow: Understanding who are leaving and why Customers will leave you – that is a fact of life. What is important is to understand who are leaving and why. Is it low value customers who are leaving or is it your best customers? Are they leaving to competitors or because they no longer need your products and services? Topics include: Customer lifetime value models: Combining value of purchases with propensity to churn and the cost of servicing and retaining the customer. Analysing survey data. (Generally useful, but we will do a brief introduction here in the context of exit surveys.) |

What statistics can offer to Decision Makers Descriptive Statistics Basic statistics - which of the statistics (e.g. median, average, percentiles etc...) are more relevant to different distributions Graphs - significance of getting it right (e.g. how the way the graph is created reflects the decision) Variable types - what variables are easier to deal with Ceteris paribus, things are always in motion Third variable problem - how to find the real influencer Inferential Statistics Probability value - what is the meaning of P-value Repeated experiment - how to interpret repeated experiment results Data collection - you can minimize bias, but not get rid of it Understanding confidence level Statistical Thinking Decision making with limited information how to check how much information is enough prioritizing goals based on probability and potential return (benefit/cost ratio ration, decision trees) How errors add up Butterfly effect Black swans What is Schrödinger's cat and what is Newton's Apple in business Cassandra Problem - how to measure a forecast if the course of action has changed Google Flu trends - how it went wrong How decisions make forecast outdated Forecasting - methods and practicality ARIMA Why naive forecasts are usually more responsive How far a forecast should look into the past? Why more data can mean worse forecast? Statistical Methods useful for Decision Makers Describing Bivariate Data Univariate data and bivariate data Probability why things differ each time we measure them? Normal Distributions and normally distributed errors Estimation Independent sources of information and degrees of freedom Logic of Hypothesis Testing What can be proven, and why it is always the opposite what we want (Falsification) Interpreting the results of Hypothesis Testing Testing Means Power How to determine a good (and cheap) sample size False positive and false negative and why it is always a trade-off |
