run_cv: Run the bayesian model with spatial cross validation

Description

This function carries out the bayesian modeling process with spatial cross-validation as described in Allen and Kim (2020). Given a focal-competitor data frame, it appends a column with predicted growth values.

Usage

run_cv(
  focal_vs_comp,
  comp_dist,
  blocks,
  prior_param = NULL,
  run_shuffle = FALSE
)

Arguments

focal_vs_comp

data frame from create_focal_vs_comp()

comp_dist

Distance to determine which neighboring trees to a focal tree are competitors.

blocks

An sf object of a blockCV block output

prior_param

A list of {a_0, b_0, mu_0, V_0} prior hyperparameters. Defaults to a_0 = 250, b_0 = 250, mu_0 a vector of zeros of length \(p + 1\), V_0 an identity matrix of dimension \((p + 1) x (p + 1)\)

run_shuffle

boolean as to whether to run permutation test shuffle of competitor tree species within a particular focal_ID

Value

focal_vs_comp with new column of predicted growth_hat
