Compare the SPUE effort proxy with modeled suitability

Joins per-cell SPUE (calc_spue_cells()) with a model surface aggregated to the same cells (h3_raster_to_cells()), keeps cells with at least min_effort effort records, and reports Spearman's rank correlation plus a calibration table: mean model value by SPUE bin (bin 0 = target never recorded despite effort; bins 1..n_bins = quantile bins of positive SPUE).

Usage

compare_spue_sdm(spue, sdm, min_effort = 30L, n_bins = 5L)

Arguments

spue

output of calc_spue_cells().

sdm

output of h3_raster_to_cells() (cell, value).

min_effort

effort floor (default 30 records).

n_bins

number of positive-SPUE quantile bins (default 5).

Value

list with stats (n_cells, rho, p_value, frac_present), calib (bin, n_cells, spue_mean, sdm_mean, sdm_sd) and data (the joined cells).
