In drmeta: Design-Indexed Location-Scale Meta-Analysis

Map study design labels to illustrative design-robustness scores

Description

Provides a convenience mapping from design-type labels to numeric scores.

Usage

dr_from_design(
  design,
  custom_map = NULL,
  default_score = 0.25,
  warn_unknown = TRUE
)

Arguments

design	Character vector of design labels (case-insensitive).
custom_map	Optional named numeric vector overriding or extending the defaults.
default_score	Score assigned to unrecognised labels. Default 0.25.
warn_unknown	If TRUE, warn about unrecognised labels.

Details

This mapping is a demonstration default, not a validated measurement model and not a universal hierarchy of study quality. A design label does not determine the magnitude or direction of bias in a particular evidence base. For substantive work the index should be constructed for the specific synthesis, outcome, and identification problem at hand, ordinarily with dr_score, and reported under alternative defensible codings.

Value

A numeric vector of scores in [0, 1], the same length as design.

Examples

dr_from_design(c("RCT", "DiD", "OLS", "IV", "matching"))
dr_from_design("house_method", custom_map = c(house_method = 0.65))
