So, in Example 1, one might apply ×10 thinning to a chain with A = 6, reducing a sample of size 10 6 to size 10 5, treating the resulting sample as independent random samples, and calculating as a standard error. is it hereditaryWeb1 okt. 2024 · E S S = M λ 2 σ 2, where σ 2 = λ 2 + 2 ∑ k = 1 ρ k and λ 2 = var ( x) where x is a vector representing an estimate of a parameter at each MCMC iteration. Then there is the issue of how the autocorrelation, ρ, is calculated. This suggests: ρ k = cov [ x t, x t + k] var [ x t] where var [ x t] could have a denominator of M or M − 1. kesb download
