Parking space can be arranged free of charge here.
Local participants (Warwick Maths/Stats) are required to register free of charge by sending an e-mail to Olivia dot Garcia at warwick dot ac dot uk. Indicate whether you wish to participate in the optional dinner at £36.75, and any dietary requirements.
No cancellation charges apply if booking is cancelled before 16th August 2016, you will be refunded in full. If booking is cancelled after 16th August 2016 or in case of a no show there will be no refund and full charges will apply. Refunds will take 3-5 working days to process and be credited to the account that was used to pay for the booking.
High-dimensional statistical inference, by Richard Samworth (Cambridge):
Lecture 1: Classical theory
Review of the linear model, geometry of orthogonal projections, hypothesis testing, examples. Ridge regression.
Lecture 2: Modern high-dimensional statistics
Model selection via, e.g., information criteria. Definition of the Lasso and its geometry. Uniqueness of Lasso solutions. Prediction and estimation properties.
Lecture 3: The Lasso and beyond
Selection consistency of the Lasso. Computation. Brief discussion of other penalty functions, other models, e.g. grouped variables.
Lecture 4: Multiple testing and Complementary Pairs Stability Selection
Familywise error rate and Bonferroni procedure; False Discovery Rate and Benjamini--Hochberg procedure. Brief discussion of extensions. I will then use the remaining time to give an exposition of some of my own work in this area. Complementary Pairs Stability Selection is a technique for improving the performance of any existing variable selection algorithm, by aggregating the results of applying it on subsamples of the data.
