Simulation study, based on the false positive rate of 0.05, to determine ﹩\mbox{ncp}\_\mbox{prior}﹩ = −log(γ) for binned data. Contours of this parameter are shown as a function of the number of bins and number of data points (logarithmic x- and y-axes, respectively). The heavy dashed line indicates the undesirable region where the numbers of bins and data points are equal.
