Reposted by Rui-Yang ZhangSam Power @spmontecarlo.bsky.social · 27/11/2025Usual MCMC algorithms are typically guaranteed to work well when used to sample from target distributions for which i) mass is reasonably well-concentrated in the centre of the state space, and ii) the log-density is smooth and of moderate growth. Outside of this setting, things can go poorly. 1336

Rui-Yang Zhang @ryzhang.bsky.social · 07/11/2025Preferential Sampling refers to scenarios where observation locations are confounded by the field of interest which the same observations are used to infer.
