data appeared to be more precisely estimated (smaller coefficients of variation and smaller estimates of sampling variance in the HC05). Plotted SSDs (Figs. 1-5) show some evidence of lack-of-fit for the data set generated from a mixture of surrogates and for the empirical data, however, p-values from goodness of fit tests did not show significant lack of fit. However, variances in the SSDs for predicted values were generally much smaller than the variance in the SSD for empirical test results. The variance of the distribution fit using all predicted values was closer to that of the empirical test results. Cross-tabulation of predicted values with empirical test results show that Web ICE predictions were positively correlated with empirically measured toxicity values (correlation coefficients on the order of 0.7 0.8) for bluegill and fathead minnow. The rainbow trout – predicted values and the mixed dataset produced non-significant negative correlations with empirical test results. The discrepancy between predicted and tested values was positively correlated with toxicity distance for the rainbow trout and fathead minnow predicted datasets. I.
