"My Statistical Consulting Project was Declared Unconstitutional– And I’m Partly Glad"

Dave Hunter, Professor of Statistics, Penn State Department of Statistics Public Lecture Series "My Statistical Consulting Project was Declared Unconstitutional– And I’m Partly Glad" Hunter’s almost-entirely-nontechnical talk will first introduce and discuss clustering, which is generally defined as organizing a collection of objects into categories based on a set of measurements. Statisticians frequently adopt what is called a model-based approach to clustering, which subtly alters the notion of what clustering means. Hunter will illustrate this point of view using a simple example, based on a 1975 photo taken in front of Old Main, of what is called "unsupervised" clustering. He will also describe an example of "supervised" clustering, involving college admissions and a hotly contested legal issue that he worked on as a graduate student in the late 1990s. The legal case ultimately led to a decision by the United States Supreme Court that, among other things, declared the model Hunter had constructed unconstitutional. But while Hunter said he is unhappy about the decision itself, the fact that the case could be argued at all has positive implications for our increasingly data-dependent society. Hunter concludes his talk with examples where obscurity in the model-building aspect of clustering can lead to unfortunate societal outcomes.
