PESTO Ensemble Manifest (Constructor)

Lightweight constructor for a posterior-predictive ensemble produced by PESTO (or any compatible UQ engine). Bundles a posterior-predictive sample matrix with optional held-out observations and free-form metadata, providing a stable interface for mmd_ppc() and other downstream verdict-layer tools.

Usage

pesto_ensemble(posterior, observed = NULL, metadata = list())

Arguments

posterior

Numeric matrix M x d: M posterior-predictive draws over d output dimensions (e.g. yield, biomass).

observed

Optional numeric matrix n_obs x d of held-out observations. May be NULL when observations are supplied later to mmd_ppc().

metadata

Optional named list of free-form metadata (run id, ensemble seed, holdout year, etc.).

Value

An object of class "pesto_ensemble".

Details

This is the kernR-side schema for the cross-package contract; until PESTO ships its native manifest emitter, callers can construct the object directly from in-memory matrices.

Examples

set.seed(1)
post <- matrix(stats::rnorm(200L), ncol = 2L)
obs  <- matrix(stats::rnorm(20L),  ncol = 2L)
ens  <- pesto_ensemble(post, obs, metadata = list(holdout_year = 2018))
