Mixture-based Nonparametric Estimation of Spatial Covariance Functions with Applications to HIV Key Population Size Estimation across Sub-Saharan Africa
Manushi Siriwardana, Hyebin Song, Le Bao +1
Consistent data on the sizes of key populations, such as female sex workers (FSWs), are often scarce, particularly at the sub-national level. Accurate size estimates are critical t…

Weighted shape-constrained estimation for the autocovariance sequence from a reversible Markov chain
Hyebin Song, Stephen Berg
We present a novel weighted projection method for estimating autocovariance sequences and spectral density functions from reversible Markov chains. Berg and Song (2023) in…

Multivariate moment least-squares estimators for reversible Markov chains
Hyebin Song, Stephen Berg
Markov chain Monte Carlo (MCMC) is a commonly used method for approximating expectations with respect to probability distributions. Uncertainty assessment for MCMC estimators is es…
