Default cutoff thresholds for shape_category classification

Returns the named list of thresholds used to map the continuous monotonicity (M) and convexity (C) indices (plus inflection counts) into a discrete shape_category. Expose so callers can override individual thresholds or pass a fully custom list to janusplot() / janusplot_shape_metrics().

Usage

janusplot_shape_cutoffs(...)

Arguments

...

Optional named overrides to merge into the defaults.

Value

A named list with numeric thresholds:

mono_strong

|M| threshold for a strictly monotone smooth (default 0.9).

mono_mod

|M| threshold for a curved-but-monotone smooth (default 0.5).

mono_nonmono

|M| below this is considered non-monotone (default 0.3).

mono_s

|M| threshold for labelling an S-shape (default 0.5).

curv_low

|C| below this is considered near-linear curvature (default 0.2).

curv_mod

|C| threshold for a clearly curved monotone (default 0.5).

curv_strong

|C| threshold for a U-shape / inverted-U shape (default 0.5).

flat

range(fit) / sd(y) below this is called flat (default 0.05).
