Oh the Places You'll Go:  The Surprising Complexity of Statistics' Most Basic Model

Abstract: A Bernoulli distribution describes a process which has only two outcomes. Despite the simplicity, it is used in a wide array of applications including a simple coin toss, the outcome of a sporting event, weather models, and the winner of an election. A careful analysis of the Bernoulli distribution also raises a number of theoretical questions leading to topics such as Bayesian inference, minimaxity and estimator theory. Fortunately, the relatively uncomplicated nature of the Bernoulli model allows such questions to be studied without the advanced mathematical machinery required for a more general treatment. This talk will explore these practical and theoretical considerations, with a focus towards the `big questions' which continue to guide modern statistical research. Two real datasets, from baseball and medicine, will be used throughout to guide the discussion.

 Tuesday, February 10, 2015 - Colloquium Talk

Cristina Ballantine, College of the Holy Cross

 Rolle's Theorem for Polynomials over Finite Fields

 Abstract:  Rolle's Theorem from calculus says that a differentiable function f that takes the same value at two different points must have a horizontal tangent line between them.  As a consequence, between any two zeros of f there must be a zero of its derivative function f'.

Is Rolle's Theorem still true if f is a polynomial and the coefficients of f live in a world different from the real numbers?  We will investigate what happens if this new world is a finite field ( a finite set in which you can still perform operations similar to addition, subtraction, multiplication and division).

 No background beyond linear algebra is needed for this talk.

4:30 pm in Seeley Mudd 207 with refreshments in Seeley Mudd 208 at 4:00 pm.

Note: The room for the talk has been updated to SM 207. Due to multiple talks scheduled at once, we will update if the room changes.

 Recent Lunch for Women in STEM

Twenty women math, statistics, and science majors enjoyed a catered lunch with a panel of three alumni on Friday, October 24, discussing graduate school and pathways into different careers. The alumni panel included:

Hannah Suh (class of 2001, now an actuary at New York Life Insurance Company)

Ilse van Meerbeek (class of 2007, now an engineering grad student at Cornell)

Melissa Moulton (class of 2009, now an oceanography grad student at MIT/Woods Hole)

The alumni offered great advice to the students, encouraging them to explore their options and chat with people working in different careers to discover which opportunities might be a good fit. All three recommended trying new directions and not to worry about immediately fixing on a path directly out of college. Their own paths after graduation provided them with a wide variety of experiences, before they each found the right fit for a career.

Funding for the event was provided by the Dean of Faculty’s office and the Clare Boothe Luce Foundation.

Hamed Ibrahim ‘09

Dept. of Civil and Environmental Engineering, Mathematical Methods in Hydrology

The object of this talk is to describe the use of mathematics in hydrology, the study of water on earth and in the atmosphere. We will use observation to establish basic physical principles for our analytical treatment of how water moves. Next we derive the equation for the motion of water underground and show that in the case where there are no bubbles in the water (incompressible) the motion of water underground is similar to the motion of heat and electricity. Then we come to the surface and consider motion in the oceans and atmosphere, where water and air often mix and move together, and so here we allow for bubbles in the water (compressible). We derive equations that are used to approximate motion in the oceans and atmosphere. Lastly, we discuss exchange of water between the oceans and the atmosphere (precipitation and evaporation) and conclude with the role of computer models in hydrologic investigations. No prior background beyond calculus one and basic knowledge of matrices is needed for this talk.

Statistical Analysis of Big Genetics and Genomics Data

CVC colloquium: Monday, November 16, 2015 4:30pm, SMUDD 206, refreshments 4pm in SMUDD 208

Xihong Lin, Department of Biostatistics, Harvard T.H. Chan School of Public Health

Abstract: The human genome project in conjunction with the rapid advance of high throughput technology has transformed the landscape of health science research. The genetic and genomic era provides an unprecedented promise of understanding genetic underpinnings of complex diseases or traits, studying gene-environment interactions, predicting disease risk, and improving prevention and intervention, and advancing precision medicine. A large number of genome-wide association studies conducted in the last ten years have identified over 1,000 common genetic variants that are associated with many complex diseases and traits. Massive targeted, whole exome and whole genome sequencing data as well as different types of -omics data have become rapidly available in the last few years. These massive genetic and genomic data present many exciting opportunities as well as challenges in data analysis and result interpretation. They also call for more interdisciplinary knowledge and research, e.g., in statistics, machine learning, data curation, molecular biology, genetic epidemiology and clinical science. In this talk, I will discuss analysis strategies for some of these challenges, including rare variant analysis of whole-genome sequencing association studies; analysis of multiple phenotypes (pleiotropy), and integrative analysis of different types of genetic and genomic data.

Causal Inference: Identifying Subgroups by their Response to Treatment

Statistics Colloquium: Thursday, October 22 7:30pm, SMUDD 206

Sarah Anoke, Department of Biostatistics, Harvard T.H. Chan School of Public Health

Abstract: Causal inference is a field of statistics focused on measuring a particular type of relationship between two variables. Referring to these two variables as the `treatment’ and the `outcome’, we consider the value that an individual’s outcome would take if the treatment was present, and the value that the individual’s outcome would take if the treatment was absent. The difference in these two potential outcomes is the treatment effect. Every individual has their own individual treatment effect (ITE). But because only one of these two potential outcomes is observable, ITEs cannot be estimated from observed data. To overcome this problem, the average outcome among a group of individuals unexposed to treatment is subtracted from the average outcome among a group of individuals exposed to treatment, yielding an average treatment effect (ATE). It is of interest to identify subgroups for which the subgroup-specific ATE is very different from the overall ATE. Knowing the overall ATE is arguably misleading; we would prefer to know that the drug has no effect within women but a dramatic effect within men. How then, can the data tell us which subgroups respond particularly well or poorly to treatment, without advance knowledge of these subgroups?

Statistical Tools and Challenges for Monitoring Migratory Birds

Statistics Colloquium: Friday, October 30th 2:00pmpm, Amherst College Frost Library 211

Emily Silverman, Statistician, Division of Migratory Bird Management, U.S. Fish & Wildlife Service

Abstract: Federal management of migratory birds began 100 years ago, when the United States signed the 1916 Convention for the Protection of Migratory Birds with Great Britain (for Canada).  These protections were codified in the Migratory Bird Treaty Act (MBTA) of 1918, which now covers over 800 species of birds, and stands as one of the earliest U.S. environmental laws.  The evolution of management approaches since the MBTA has led to the development of monitoring programs and quantitative methods in wildlife science. I will present the history of bird monitoring and statistical methods for population assessment and will discuss new approaches, challenges, and how a solid understanding of statistical concepts is essential for informed management.  Drawing on examples from my own work, I will highlight the interdisciplinary skills needed to operate effectively as a scientist and statistician in a resource management agency.  As our ability to collect information about the natural world expands in an increasingly digital world, the need for innovative, technically-adept wildlife scientists is expanding.
