fastFGEE: Fast Functional Generalized Estimating Equations via a One-Step
Estimator
Fits functional generalized estimating equations for longitudinal
functional outcomes and covariates using a one-step estimator that is fast
even for large cluster sizes or large numbers of clusters. The package
supports quasi-likelihoods derived from a range of families, common link
functions, and several working correlation structures. Uncertainty
quantification is based on sandwich variance estimators and bootstrap
procedures that remain valid even when the working correlation is
incorrectly specified. The package provides an implementation of the
method described in Loewinger et al. (2025) <https://pmc.ncbi.nlm.nih.gov/articles/PMC12306803/>. For irregularly spaced AR(1) precision matrices, the package can optionally use
the archived package 'irregulAR1'; if needed, it can be obtained from the CRAN
Archive at <https://cran.r-project.org/src/contrib/Archive/irregulAR1/>.
