"Recent Advancements in Changepoint Analysis"

Abstract: Changepoint methods are crucial in time series analysis. This presentation begins with an overview of current mean shift changepoint techniques, including Wild Binary Segmentation (WBS) and Pruned Exact Linear Time (PELT), highlighting their strengths and limitations. It then explores recent research findings on changepoint detection in complex model structures, illuminating the latest advancements in the field within the changepoint community. This talk is based on collaborative work with esteemed colleagues: Drs. Rebecca Killick, Colin Gallagher, and Robert Lund.
