Factor relating a density measure to a density with respect to weight

Description

Writing N_w for the density with respect to weight, the density with respect to measure m is N_w times the factor returned here. With the allometric weight-length relationship w = a l^b these factors are 1 for "w", w for "log_w", dw/dl = b w / l for "l" and l\,dw/dl = b w for "log_l".

Usage

density_measure_weight(measure, w, l, b)

Arguments

measure	One of density_measures.
w, l, b	Numeric vectors of the same length giving the weight, the corresponding length, and the exponent of the weight-length relationship.

Value

A numeric vector of factors.
