Primate species in which the neonatal brain size is large relative to the birth canal tend to have more sexually dimorphic pelves: this is a classic comparative relation, discovered by Schultz and Leutenegger. The original work did not correct for phylogenetic nonindependence of the data points; it only partly corrected for body size; it used ratios in both variables, and the size of the female pubis featured in both x- and y-variables. A recent publication by Tague placed a question mark over the validity of the relation. I therefore retested it, correcting for all four statistical defects. A strongly significant statistical relation exists.
这是舒尔茨和洛伊滕内格发现的经典比较关系。最初的研究没有对数据点的系统发育非独立性进行校正；仅部分校正了体型；两个变量都使用了比率，并且雌性耻骨的大小同时出现在x变量和y变量中。塔格最近发表的一篇论文对这种关系的有效性提出了质疑。因此，我对其进行了重新检验，校正了所有四个统计缺陷。结果发现存在显著的统计关系。
