A comparison of the relationships between the modeled and measured RGC densities. (A) Application of the NLM described by equations 1 – 3 and (B) application of the LM described by equations 4 and 5 for the translation between SAP visual sensitivity and RGC density that were used to obtain the predicted RGC densities. Symbols for data for each of the 4 eccentricities are indicated by the symbol legend. For each method of relating visual sensitivity to neuron density, the 1:1 relationship is illustrated by the solid line and the 95% limits of agreement are illustrated by the dashed lines. The upper inset histograms present the residual errors between modeled and measured data, with the mean residual deviation (MRD) and the standard deviation (SD) of the distribution shown on the graph. Other statistical goodness-of-fit indices that are inset to the graph represent the coefficient of determination (R2), the mean absolute deviation (MAD), and root mean squared deviation (RMSD)
