Compute MESS (Multivariate Environmental Similarity Surface)

Measures how similar each cell is to the training environment. Negative values indicate novel (non-analog) conditions.

Usage

compute_mess(grid_ptrs, reference_values, feature_names)

Arguments

grid_ptrs

List of external pointers to Grid<float> objects.

reference_values

List of numeric vectors with reference values for each variable (e.g. values at training sites).

feature_names

Character vector of variable names.

Value

A named list with:

mess_grid

External pointer to Grid<float> with MESS values

mod_grid

External pointer to Grid<float> with MoD variable index (1-based)
