Predictive Models in Health Research
Lasso, Random Forests, and especially Deep Neural Networks are very popular in data science applications. Do they have a role in health research, and are they likely to replace more traditional statistical models? In this talk I will argue that it depends on the application, the amount of data available, and the purpose of the modeling, with some guidance from the "Occam's razor" principle.
Trevor Hastie was born in South Africa in 1953. He received his university education from Rhodes University, South Africa (BS), University of Cape Town (MS), and Stanford University (Ph.D Statistics 1984).
His first employment was with the South African Medical Research Council in 1977, during which time he earned his MS from UCT. In 1979 he spent a year interning at the London School of Hygiene and Tropical Medicine, the Johnson Space Center in Houston Texas, and the Biomath department at Oxford University. He joined the Ph.D program at Stanford University in 1980. After graduating from Stanford in 1984, he returned to South Africa for a year with his earlier employer SA Medical Research Council. He returned to the USA in March 1986 and joined the statistics and data analysis research group at what was then AT&T Bell Laboratories in Murray Hill, New Jersey. After eight years at Bell Labs, he returned to Stanford University in 1994 as Professor in Statistics and Biostatistics. In 2013 he was named the John A. Overdeck Professor of Mathematical Sciences, and in 2018 was elected to the National Academy of Sciences.
His main research contributions have been in applied statistics; he has published over 200 articles and written five books in this area: "Generalized Additive Models" (with R. Tibshirani, Chapman and Hall, 1991), "Elements of Statistical Learning" (with R. Tibshirani and J. Friedman, Springer 2001; second edition 2009), "An Introduction to Statistical Learning, with Applications in R" (with G. James, D. Witten and R. Tibshirani, Springer 2013) and "Statistical Learning with Sparsity" (with R. Tibshirani and M. Wainwright, Chapman and Hall, 2015) and "Computer Age Statistical Inference" (with Bradley Efron, Cambridge 2016). He has also made contributions in statistical computing, co-editing (with J. Chambers) a large software library on modeling tools in the S language ("Statistical Models in S", Wadsworth, 1992), which form the foundation for much of the statistical modeling in R. His current research focuses on applied statistical modeling and prediction problems in biology and genomics, medicine and industry.
David A. Sprott (1930-2013)
Professor David Sprott was the first Chair (1967-1975) of the Department of Statistics and Actuarial Science at the University of Waterloo and first Dean of the Faculty of Mathematics (1967-1972). The David Sprott Distinguished Lecture Series was created in recognition of his tremendous leadership at a formative time of our department, as well as his highly influential research in statistical science.Distinguished Lecture Poster
