R: Objects to use in examples and tests

example_loglik_array {loo} | R Documentation

## 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, ])
