sensitivity_reference: Sensitivity of the LTG-SMD to the choice of target reference

In ltgsmd: Latent True-Score and Target-Population Anchored Geometric SMD

Sensitivity of the LTG-SMD to the choice of target reference

Description

Recomputes the LTG-SMD under each of several user-supplied alternative reference data frames. Useful when more than one target reference is defensible (Section 8.3 of the companion paper).

Usage

sensitivity_reference(
  object,
  alternative_references,
  study_data,
  group_var,
  score_var = NULL,
  items = NULL,
  group_levels = NULL,
  rho_external = NULL
)

Arguments

object	An "ltg_smd" object computed with a primary reference.
alternative_references	A named list of reference data frames. Names are used as labels in the output.
study_data	Original study data (required to recompute).
group_var, score_var, items, group_levels, rho_external	Arguments to pass through to compute_ltg_smd().

Value

A data frame with columns reference, ltg_smd, c_focal, c_reference, rho_focal, rho_reference, including the primary reference in the first row.
