Figure 3.
Plots of parameter values recovered from fitting the diffusion model to simulated data from Simulation Study 1 plotted against the model parameters used to generate the simulated data. Plots are for boundary separation, nondecision time, and the highest drift rate for the numerosity design with 1000 observations and with 40 observations per condition. The different columns are for the chi-square method with 9 quantiles and the EZ method with either 0 or 4% contaminants. The correlations are shown in the top right corner of each plot and the diagonal line has slope 1 and intercept zero.
