Fig. 4.
Trace plot and marginal density for parameter β of the difference between groups (Dyslexics vs. Non-dyslexics) in mean FA values. (A–C) Left CR. (B–D) Right CR. Estimates were generated from 10,000 iterations, in one chain, with thinning interval of one (i.e., no data point discarded). Both trace plots (the values parameter β took during the runtime of the chain) and marginal densities (smoothed histograms of parameter β values) indicated that the difference between groups was practically null.
