title: Allometry and multivariate growth.
abstract: Multivariate allometry, and conservative and nonconservative growth models are generalized by a set of global differential equations, preserving the linear trajectory property. Linear least squares methods are exposited for estimation of parameters, comparing special cases and drawing qualitative conclusions. Three classical sets of data are analyzed in detail, illustrating the usefulness and simplicity of the method.
