Proportion of overlap between the posterior chains for estimates of parameters of interest from the BLCM where 0 reflects completely separate and 1 reflects completely overlapping distributions (49).

b

Mean of difference between pairs of posterior samples from the BLCMs (first parameter listed-second parameter).
