Figure 3. Fits of all 14 models to the data in Fig. 1B-C (axis labels and scales as there).

VP  =  variable precision; EP  =  equal precision; AP  =  average precision; SP  =  single precision. Error bars and shaded areas represent ±1 s.e.m. in the data and the model, respectively. The number in each plot is the R ² of the fit (for the left plot in each pair, computed over false-alarm rates and unconditioned hit rates). Frame color indicates model goodness of fit relative to the winning model, as obtained from Bayesian model comparison (Fig. 4).
