abstract: 'Fits multivariate Gaussian-mixture proxies to target distributions on real
  Euclidean space, given by a density, by samples, or by a characteristic function.
  Four fitting regimes are unified under one verb: (i) closed-form moment matching
  for a single component, (ii) classical expectation-maximisation when independent
  samples are available, (iii) importance-sampled expectation-maximisation that minimises
  the Kullback-Leibler divergence when the target can be evaluated point-wise but
  not (cheaply) sampled, and (iv) a least-squares fit to the characteristic function
  when only that is known, with numerical bounds on the Kolmogorov distance along
  one-dimensional projections. Closed-form Gaussian-mixture operators (density, sampling,
  marginalisation, conditioning, divergence) round out the toolkit. The conditioning
  operator drives multiple imputation of data missing at random, covering the multimodal
  and heteroscedastic cases a single-Gaussian model cannot represent. Implements the
  regime hierarchy of van der Hoek and Elliott (2024) <https://doi.org/10.1080/07362994.2024.2372605>.'
