psAve: Model-Averaged Propensity Scores Selected by Prognostic-Score Balance

Constructs a model-averaged propensity score as a convex combination of candidate propensity score models, with mixing weights selected on a simplex grid to optimize covariate or prognostic-score balance, implementing the method of Kabata, Stuart and Shintani (2024) <doi:10.1186/s12874-024-02350-y>. Prognostic scores follow Hansen (2008) <doi:10.1093/biomet/asn004>: outcome models are fit on untreated units only. The resulting score is designed to be supplied directly to the matchit() function of 'MatchIt' as a distance measure or to the weightit() function of 'WeightIt' as a propensity score, with balance assessment via 'cobalt'.

Method details and design decisions
Notation | The simplex grid and tie-breaking | Step 1: Candidate models | Step 2: $\gamma$ — the model-averaged prognostic score | Step 3: $\lambda$ — the model-averaged propensity score | criterion = "logloss" | criterion = "smd" | criterion = "ks" | criterion = "prog" (the default; the paper's "Prog (Ave)") | Vertex mode | Criterion vs. display conventions for the SMD denominator | Five documented fixes relative to the paper's reference code | Relation to other software | Limitations | References
