Statistical Analysis for Studies of Intraocular Lens Formula Accuracy
[...]a cubic root transformation gives the same weight to a change in prediction error from 0.00 diopter (D) to 0.10 D as from 0.10 D to 0.60 D. The preferred method to statistically analyze absolute errors is nonparametric tests. If the P value is statistically significant, post hoc analysis can be...
