Calculate the sensitivity of a function at the median

This function evaluates the sensitivity of a model to a parameter. This is done by evaluating the first derivative of the univariate spline estimate of the model response at the parameter median.

Usage

get.sensitivity(trait.samples, sa.splinefun)

Arguments

trait.samples

parameter values to evaluate at their median

sa.splinefun

fitted spline function. Must take two arguments.

Value

numeric estimate of model sensitivity to parameter
