Under conditions similar to the ones existing for HMC, we also show that NUTS is geometrically ergodic.

The resulting estimator leads to inference without a bias from the time-discretisation as the number of Markov chain iterations increases.

This complements the earlier findings in the literature for conditional particle filters, which assume the number of particles to grow (super)linearly in terms of the time horizon.

Under general conditions, essentially when MLMC admits the canonical square root Monte Carlo error rate, the proposed new schemes are shown to be asymptotically as efficient as MLMC, both in terms of variance and cost.
