Extended staying alive theory (SAT) raises the issue of the extent to which its various attributes are linked or whether they provide alternative means to the same adaptive ends. Theories such as SAT that consider an array of sex differences may benefit from the application of the multivariate D statistic, rather than using a series of d values, as is common at present.
