关于3，很多人心中都有不少疑问。本文将从专业角度出发，逐一为您解答最核心的问题。
问：关于3的核心要素，专家怎么看？ 答：To sample the posterior distribution, there are a few MCMC algorithms (pyMC uses the NUTS algorithm), but here I will focus on the Metropolis algorithm which I have used before to solve the Ising spin model. The algorithm starts from some point in parameter space θ0\theta_0θ0. Then at every time step ttt, the algorithm proposes a new point θt+1\theta_{t+1}θt+1 which is accepted with probability min(1,P(θt+1∣X)P(θt∣X))\min\left(1, \frac{P(\theta_{t+1}|X)}{P(\theta_t|X)}\right)min(1,P(θt∣X)P(θt+1∣X)). Because this probability only depends on the ratio of posterior distributions, it is independent on the normalization term P(X)P(X)P(X) and instead only depends on the likelihood and the prior distributions. This is a huge advantage since both of them are usually well-known and easy to compute. The algorithm continues for some time, until the chain converges to the posterior distribution, and the observed data points show the shape of the posterior distribution.
