Researchers have developed new statistical methods for federated linear stochastic approximation (LSA), providing the first federated Gaussian approximations that account for communication-computation trade-offs and data heterogeneity. These findings quantify the impact of local step sizes and update counts on convergence rates. The work also introduces an online multiplier bootstrap procedure for statistical inference on the final model iterate, offering non-asymptotic validity guarantees. AI
