supp_mat_1_code: code to implement bias adjustments and other analyses described in the paper
supp_mat_2_data sheet 1: per-period means. p = period, est = estimate, type = type of adjustment, lower = lower bound of 95% confidence/credible interval, upper = upper bound of confidence/credible interval, adjusted = whether or not the estimate was adjusted or naive and AE = absolute error from the population values. 
supp_mat_2_data sheet 2: trends. AE is error rather than absolute error.
supp_mat_2_data sheet 3: Mean absolute errors from unadjusted and adjusted sample vs population distributions of auxiliary variables. mae_samp = sample mae, mae_est = adjusted sample mae, variable = auxiliar variable
