"On Information Quality": seminar at Indian Statistical Institute
I'll present a talk "On Information Quality" at the Indian Statistical Institute in Kolkata's Bayesian & Interdisciplinary Research Unit on February 19th (4:15pm at BIRU conference room, 4th floor of R.A. Fisher Bhavan). Abstract: We define the concept of information quality ‘InfoQ’ as the potential of a data set to achieve a specific (scientific or practical) goal by using a given empirical analysis method. InfoQ is different from data quality and analysis quality, but is dependent on these components and on the relationship between them.We survey statistical methods for increasing InfoQ at the study design and post-data-collection stages, and we consider them relatively to what we define as InfoQ.We propose eight dimensions that help to assess InfoQ: data resolution, data structure, data integration, temporal relevance, generalizability , chronology of data and goal, construct operationalization and communication.We demonstrate the concept of InfoQ, its components (what it is) and assessment (how it is achieved) through three case-studies in on-line auctions research. We suggest that formalizing the concept of InfoQ can help to increase the value of statistical analysis, and data mining both methodologically and practically, thus contributing to a general theory of applied statistics.

New student projects uploaded
Last term I instructed over 200 students in two courses: "Business Analytics Using Data Mining" and "Forecasting Analytics". In each of the courses, students worked in teams on a project using real data, formulating a business problem and addressing it with data mining and/or forecasting tools. I have posted the top projects in the Students Projects area of my website (look for the 2013 projects). For each project, I posted the team's presentation slides and report.
This year, many teams used data from a cab aggregation service in Bangalore called YourCabs.com. The data were shared with us by Mr. Rajath Kedilaya, co-founder of YourCabs. Other teams used data from a hypermarket in India.
