The model separates global and local grand means, row and column main effects, and bilinear interaction components, allowing nonstationary main effects under suitable conditions. A circular-shift bootstrap is used to detect a shared global common component and screen participating groups on a stationary segment. The underlying methodology is developed in Liu, Lam and Cen (2026) <doi:10.48550/arXiv.2610.18335>.https://github.com/r-universe/kx-liu/actions/runs/41836454057Wed, 21 Oct 2026 15:58:50 GMTMMEFM0.1.1successhttps://kx-liu.r-universe.devhttps://github.com/kx-liu/mmefmgetting-started.Rmdgetting-started.htmlGetting started with MMEFM2026-10-08 10:13:542026-10-21 15:47:18
