PSinference provides exact finite-sample inferential procedures for singly and multiply released plug-in sampling (PS) synthetic datasets under a multivariate normal model. The key insight is simple: an analyst who receives \(M\) independent synthetic datasets \(V_1, \ldots, V_M\) of size \(n\) naturally treats all released data as a whole by stacking them into a single dataset of size \(Mn\). This stacking is statistically justified — the \(Mn\) rows are conditionally i.i.d. given the original data — and immediately extends the exact procedures of Klein et al. (2021) to arbitrary \(M \geq 1\) via the substitution \(n \to Mn\).
