The first value is based on the correlation criterion, the second on the bias criterion, and the third on the estimation precision criterion. In the five-parameter model, the intertrial variabilities sν and szr are fixed at zero, in the four-parameter model additionally the intertrial variability st0 is fixed at zero and in the three-parameter model also the starting point zr is fixed (zr = 0.5). For conditions with 95% quantiles of parameter estimation precision (weighted against the best possible accuracy) exceeding 25, values are depicted in gray. On the basis of data sets with at least 4% of trials at each threshold.
