Shown are mean signed difference (MSD) and mean absolute difference (MAD) of various estimation methods compared with the exact value, obtained by brute force. Formulas for T^K, h^K, and LK are given in Equations 9, 4, and 5, respectively. Values are shown in log space (columns 2–7) and linear space after exponentiating and normalizing to sum to 1 (columns 8–13). Values of K here denote the value used in the inference step, with each row being an average over 1000 simulations (a more detailed breakdown can be found in Table S1).
