Validate and apply scaling (engine-friendly)

Usage

validate_and_apply_nmar_scaling(
  standardize,
  has_aux,
  response_model_matrix_unscaled,
  aux_matrix_unscaled,
  mu_x_unscaled,
  weights = NULL,
  weight_mask = NULL
)

Arguments

standardize: logical; apply standardization if TRUE.
has_aux: logical; whether the engine uses auxiliary constraints.
response_model_matrix_unscaled: response model matrix (with intercept).
aux_matrix_unscaled: auxiliary matrix (no intercept) or an empty matrix.
mu_x_unscaled: named auxiliary means on original scale, or NULL.
weights: Optional numeric vector used for weighted scaling.
weight_mask: Optional logical mask or nonnegative numeric multipliers applied to weights.

Value

A list with components nmar_scaling_recipe, response_model_matrix_scaled, auxiliary_matrix_scaled, and mu_x_scaled.
