  1. Table detailing the relationships between the 16 test data points and the four estimating functions. Although all four functions failed to predict 7 models to within a factor of 10 of their actual number of ExPas, the function f2 (θ1) had the least range for over- and under-estimation. Rows representing information of estimating functions using factors θ1 and θ2, respectively, in the top two and bottom two rows. The cell corresponding to the highest correlation, r, is emphasized by an asterisk (*).
