Difficult Probability Problem: Distribution of Digits in Rogue Systems

I recently posted a table summarizing probabilistic properties of digits in various number representation systems, see here.  The topic is already rather difficult for well-behaved systems (those listed in my table) but some systems are rogue, and do not have these nice statistical properties. Here we focus on one of these less known systems,…

Topology Data Analysis (TDA)

Topology is the branch of pure mathematics that studies the notion of shape.  In the context of large, complex, and high dimensional data sets, topology takes on two main tasks, the measurement of shape and the representation of shape.  One can measure shape related properties within the data, and create compressed representations of data sets retaining features which reflect the relationships among the points in the data set. The…

Building a Data Quality Strategy

In this article I explore some of the key concepts of data quality management and how to build a strategy for continuous improvement. I won’t be covering every possible scenario, process, method or problem; only those that are common across most industries and those that have proved useful on my own personal journey.

Hopefully, we already agree that good data quality is an essential part of business intelligence and a foundation on which you build your systems, processes and…

Double-Yolk "Bayesian Egg": Bayes, Frequentist and a 250 years-old puzzle

The Backdrop. Bayesians and Frequentists have long been ambivalent toward each other. The concept of “Prior” remains the center of this 250 years old tug-of-war: frequentists view prior as a weakness that can cloud the final inference, whereas Bayesians view it as a strength to incorporate expert knowledge into the data analysis. So, the question naturally arises, how can we develop a Bayes-frequentist consolidated data analysis workflow that enjoys the best…

New Marketing Insight from Unsupervised Bayesian Belief Networks

Introduction

“Limited-Service Restaurants” (LSRs) is how the restaurant industry refers collectively to fast food and fast-casual dining establishments.  Marketers who specialize in LSRs often employ marketing research to evaluate hypotheses about their brands or to detect segments within their markets.  An important additional purpose of market research is to understand the total structure of a market, to find out what guests consider important…

Adding Program Evaluation to the Data Science Curriculum

We tried to do XYZ. Did it make a difference?”

Whether you are in the for-profit world or the not-for profit world, this is a very basic question that many people try to answer.  

You could be working at a bank trying to figure out which offer is most appealing to customers, at an online retailer figuring out which ad display gets the most clicks, at the Department of Education trying to test the effect of smaller class sizes, at the city government office trying to see if the…

Data Science Simplified Part 11: Logistic Regression

In the last blog post of this series, we discussed classifiers. The categories of classifiers and how they are evaluated were discussed. We have also discussed regression models in depth. In this post, we dwell a little deeper in how regression models can be used for classification tasks.

Logistic Regression is a widely used regression model used for classification tasks. As usual, we will discuss by example. No Money bank approaches us with a problem. The bank wants…
