Changes one already-scaled predictor by a declared scale factor and requires an explicit coefficient-prior scale for the new parameterisation. This avoids pretending that a common coefficient prior is automatically invariant to predictor scaling.

Usage

create_predictor_scaling_sensitivity_specification(
  specification,
  predictor,
  scale_factor,
  coefficient_scale,
  interaction_scale = NULL
)

Arguments

specification

An approved model specification.

predictor

A declared predictor that was scaled during preparation.

scale_factor

New scale divided by the original recorded scale. Values above one make the transformed predictor numerically smaller.

coefficient_scale

Explicit population-coefficient prior scale under the alternative parameterisation.

interaction_scale

Optional explicit interaction prior scale when the advanced separate-interaction prior is used.

Value

An approved alternative specification.
