Return the full internal reference table — grass_reference

For inspection, custom interpolation, or reproducibility. In the paper this is the prevalence-conditioned threshold table.

Usage

grass_reference_table(reference_level = NULL)

Arguments

reference_level: Optional numeric band (0.70, 0.80, 0.85, or 0.90). If supplied, only that band is returned. Default NULL returns all four bands in long form.

Value

A long-form data.frame with columns prevalence, reference_level, metric, reference, and J.
