compute_Bateman: Compute the Bateman gradient

In courtiol/matingRhinos: Analysis of the Mating, Reproductive Success and Their Correlates in White Rhinos

Description

This function computes the Bateman gradient. The Bateman gradient is the slope of the regression line of the reproductive success on the mating success. Following Jones 2009 (and unlike some other work), we consider the relative reproductive success and the relative mating success to compute the gradient; i.e. we divide each variable by the population mean before fitting the linear model.

Usage

compute_Bateman(mating_success, reproductive_success)

Arguments

mating_success	A vector of mating success outcomes.
reproductive_success	A vector of reproductive success outcomes.

Value

The Bateman gradient.
