描述----------Description----------
Stores the estimated posterior distributions of the latent abundance or occurrence variables.
估计后验分布存储的潜在丰度或出现变数。
类对象----------Objects from the Class----------
Objects can be created by calls of the form ranef.
可以创建对象通过调用的形式ranef。
插槽----------Slots----------
post: An array with nSites rows and Nmax
post：array nSites行和Nmax
方法----------Methods----------
bup signature(object = "unmarkedRanef"): Extract the Best Unbiased Predictors (BUPs) of the latent variables (abundance or occurrence state). Either the posterior mean or median can be
BUPsignature(object = "unmarkedRanef")：提取的最佳无偏预测因素（BUPS）的潜在变量（丰度或发生状态）。无论后平均值或中位数可以是
confint signature(object = "unmarkedRanef"): Compute
confintsignature(object = "unmarkedRanef")计算
plot signature(x = "unmarkedRanef", y = "missing"):
图signature(x = "unmarkedRanef", y = "missing")：
show signature(object = "unmarkedRanef"): Display the
显示signature(object = "unmarkedRanef")：显示
警告----------Warnings----------
Empirical Bayes methods can underestimate the variance of the posterior distribution because they do not account for uncertainty in the hyperparameters (lambda or psi). However, we have not found this to be the case in a set of limited simulations studies that can be found in the inst/unitTests directory of unmarked. Simulations do, however, indicate that the posterior mode can exhibit slight (3-5 percent) negatively bias as a point estimator of site-specific abundance. It appears to be safer to use the posterior mean even though this will not be an integer in general.
经验贝叶斯方法不能低估的后验分布的方差，因为他们没有考虑到的超（λ或psi）的不确定性。然而，我们还没有发现这是一组有限的模拟研究，可以发现在研究所/单元测试目录无人盯防的情况下。不必说什么，否则情况更糟，不过，模拟表明后的模式可以表现出轻微的（3-5％）负面的偏见特定地点的丰富的点估计。这似乎是更安全的使用后验均值即使这不会是一般的整数。
