In stan-dev/loo: Efficient Leave-One-Out Cross-Validation and WAIC for Bayesian Models

Objects to use in examples and tests

Description

Example pointwise log-likelihood objects to use in demonstrations and tests. See the Value and Examples sections below.

Usage

example_loglik_array()

example_loglik_matrix()

Value

example_loglik_array() returns a 500 (draws) x 2 (chains) x 32 (observations) pointwise log-likelihood array.

example_loglik_matrix() returns the same pointwise log-likelihood values as example_loglik_array() but reshaped into a 1000 (draws*chains) x 32 (observations) matrix.

Examples

LLarr <- example_loglik_array()
(dim_arr <- dim(LLarr))
LLmat <- example_loglik_matrix()
(dim_mat <- dim(LLmat))

all.equal(dim_mat[1], dim_arr[1] * dim_arr[2])
all.equal(dim_mat[2], dim_arr[3])

all.equal(LLarr[, 1, ], LLmat[1:500, ])
all.equal(LLarr[, 2, ], LLmat[501:1000, ])
