Generate a Valid Parameter Domain Around MAP Estimates

Creates a 2-row matrix defining the domain for each parameter, centered on MAP values, with optional margin, bounds, and a minimum enforced width.

Usage

generate_domain_from_map(
  map_vals,
  margin = 0.25,
  min_width = 0.1,
  lower_bound = 0,
  upper_bound = 2
)

Arguments

map_vals

Named numeric vector of MAP estimates (e.g. from MCMC).

margin

Numeric. Symmetric buffer to expand around each parameter (default = 0.25).

min_width

Numeric. Minimum allowable width per parameter domain (default = 0.1).

lower_bound

Numeric. Minimum allowed value for any parameter (default = 0).

upper_bound

Numeric. Maximum allowed value for any parameter (default = 2).

Value

A 2-row matrix with named columns. Row 1 = lower bounds, Row 2 = upper bounds.
