Summarise simulated DiD data as pre-post (treatment arm only) statistics

Discards all control-arm observations and returns pre/post means and SDs for the treatment arm. Produces data in the format expected by meta_did() for design "pp".

Usage

as_summary_pp(sim)

Arguments

sim

A data frame produced by simulate_meta_did().

Value

A data frame with one row per study in the format required by validate_summary_data() for design "pp".

Examples

sim <- simulate_meta_did(n_studies = 3, seed = 1)
as_summary_pp(sim)
