Simulated standardized mean difference data with multiple outcomes nested within studies. The data are used in examples for multivariate SMD workflows and methodology-adjusted substantive meta-regression.

Usage

smd_data

Format

A data frame with 14 rows and 7 columns:

study

Study identifier.

d

Observed standardized mean difference.

SE

Standard error of d.

N

Total study sample size.

nt

Treatment-group sample size.

nc

Control-group sample size.

r2do

Assumed within-study outcome correlation used when building SMD covariance matrices.

Source

Simulated for package examples; see data-raw/smd-data-sim.r in the source repository for the data-generation code.
