cevcmm: Communication-Efficient Varying Coefficient Mixed-Effects Models

Description

Scalable inference for Varying Coefficient Mixed-Effects Models (VCMMs) with large, correlated random effects. The package implements:

Details

• Sufficient-statistics (SS) iterative estimator (Algorithm 1).

• One-step communication-efficient surrogate likelihood (CSL) estimator.

• SVD-stabilized variants for ill-conditioned random-effect Gram matrices.

• Kronecker and separable covariance structures for origin-destination and group-shared random effects.

The package is in early development. See the project ROADMAP for the current status.
