The 10th and 90th percentiles, mean, and CV are indicated for each parameter. Also indicated for each parameter are its η 2 and the p value of η 2. The nine parameters in boldface had η 2 > 0.1 and p values lower than our computational limit of p = 0.0001 (probably by several orders of magnitude). All parameters are defined in Materials and Methods.
