The intervals invert a profile score statistic on the variance-covariance scale, with nuisance parameters estimated on an extended parameter set. The intervals have near-nominal coverage uniformly in the parameter, including near the boundary of the parameter space, where Wald and likelihood ratio intervals can be unreliable. The methods are described in Shedden and Ekvall (2026) <doi:10.48550/arXiv.2610.04181>, building on Ekvall and Bottai (2026) <doi:10.1093/biomet/asaf079>, Zhang, Ekvall, and Molstad (2025) <doi:10.1093/biomet/asaf010>, and Ekvall and Bottai (2022) <doi:10.1214/22-AOS2177>.https://github.com/r-universe/koekvall/actions/runs/40005180888Fri, 23 Oct 2026 18:11:34 GMTreconf0.2.0successhttps://koekvall.r-universe.devhttps://github.com/koekvall/reconffev1-example.Rmdfev1-example.htmlScore-based confidence intervals for random effect covariance parameters: FEV1 example2026-04-03 15:40:272026-10-10 14:43:02
