Abstract

Discusses statistical and biological issues that may arise in applications of Lande and Arnold's (1983) multiple-regression approach to measuring selection. In particular, multicollinearity (extreme intercorrelation of characters) and extrinsic, unmeasured factors affecting fitness may seriously complicate inference regarding selection. Violation of the assumption that residuals are normally distributed vitiates tests of significance. For this situation, applications of recently developed jackknife tests of significance are suggested. -from Authors
