Function that computes how often the true value of the parameter is included within the 95/5 high posterior density interval
id_sim_coverage(obj, rep = 1, quantiles = c(0.95, 0.05))
A fitted idealstan
object with true data generated by id_sim_gen
How many times the models were fitted on new data, currently can only be 1
What the quantile coverage of the high posterior density interval should be
