^*Algorithm D; based on 1,000 observations. Estimated SEM of T = 0.01.

^†Based on likelihoods estimated from B = 200 simulations; 1,000 observations after sampling every 100 steps. Estimated SEM of T = 0.01.

^‡Algorithm F; based on 1,000 observations after sampling every 50,000 steps. Estimated SEM of T = 0.01.
