Estimating granular house price distributions in the Australian market using Gaussian mixtures

no code implementations8 Apr 2024 Willem P Sijp, Anastasios Panagiotelis

Price indices are derived as means, medians, quantiles or other functions of the estimated distributions.

Optimal reconciliation with immutable forecasts

1 code implementation20 Apr 2022 Bohan Zhang, Yanfei Kang, Anastasios Panagiotelis, Feng Li

In this paper, we formulate reconciliation methodology that keeps forecasts of a pre-specified subset of variables unchanged or "immutable".

Computationally Efficient Learning of Statistical Manifolds

1 code implementation22 Feb 2021 Fan Cheng, Anastasios Panagiotelis, Rob J Hyndman

By exploiting the connection between Hellinger/total variation distance for discrete distributions and the L2/L1 norm, we demonstrate that the proposed distance estimators, combined with approximate nearest neighbor searching, could largely improve the computational efficiency with little to no loss in the accuracy of manifold embedding.

Updating Variational Bayes: Fast sequential posterior inference

no code implementations1 Aug 2019 Nathaniel Tomasetti, Catherine S. Forbes, Anastasios Panagiotelis

Variational Bayesian (VB) methods produce posterior inference in a time frame considerably smaller than traditional Markov Chain Monte Carlo approaches.
