vza_rescale {gaiah}R Documentation

Parametric bootstrap for rescaling a la the vander zanden appendix

Description

This is a vectorized and much more efficient implementation of the original rescale function from the Vander Zanden appendix. It takes the output of group_birds_by_location directly and does the parametric bootstrapping for vza_rescale_reps samples.

Usage

vza_rescale(SBL, vza_rescale_reps = 1000)

Arguments

SBL

the data frame that summarizes the isotope feather data and isoscape predictions at each location. This must have columns of cnt, meanH, sdH, meaniso, sdiso

vza_rescale_reps

Number of simulated regressions to do. Default is 1000.

Value

Returns a matrix with vza_rescale_reps rows. Column 1 is "intercepts" and column two is "slopes"
