Topic:Narrowest Significance Pursuit: inference for multiple change-points in linear models
Time:5:00 pm - 6:00 pm
Venue:Zoom Meeting (please refer to seminar PDF)
Category:Latest Seminars and Events
Speaker:Professor Piotr Fryzlewicz

In this talk, we introduce Narrowest Significance Pursuit (NSP), a general and flexible methodology for automatically detecting localised regions in data sequences which each must contain a change-point (understood as an abrupt change in the parameters of an underlying linear model), at a prescribed global significance level. NSP works with a wide range of distributional assumptions on the errors, and guarantees important stochastic bounds which directly yield exact desired coverage probabilities, regardless of the form or number of the regressors. In contrast to the widely studied “post-selection inference” approach, NSP paves the way for the concept of “post-inference selection”. R package nsp is available from CRAN.
