Details
详细信息----------Details----------
JK1 and JKn are jackknife schemes for unstratified and stratified designs respectively. The finite population correction may be specified as a single number, a vector with one entry per stratum, or a vector with one entry per observation (constant within strata). When fpc is a vector with one entry per stratum it may not have names that differ from the stratum identifiers (it may have no names, in which case it must be in the same order as unique(strata)). To specify population stratum sizes use fpctype="population", to specify sampling fractions use fpctype="fraction" and to specify the correction directly use fpctype="correction"
JK1和JKN是不分层，分层设计的折刀计划。有限总体修正可能被指定为一个数字，一个向量，其每一个条目阶层，或者一个向量，其每一个条目观察(恒定在地层)。当fpc是一个向量，其每一个条目地层中，它可能没有名称不同于地层标识符的(它可能没有名字，在这种情况下，它必须是在相同的顺序unique(strata))。要指定人口阶层的尺寸使用fpctype="population"，指定抽样比使用fpctype="fraction"指定校正直接使用fpctype="correction"
The only reason not to use compress=TRUE is that it is new and there is a greater possibility of bugs. It reduces the number of rows of the replicate weights matrix from the number of observations to the number of PSUs.
唯一的不使用compress=TRUE的原因是，它是新的，有一个更大的错误的可能性。行的复制权重矩阵的若干意见的PSU的数量大大减少了。
In BRR variance estimation each stratum is split in two to give half-samples. Balanced replicated weights are needed, where observations in two different strata end up in the same half stratum as often as in different half-strata.BRR, strictly speaking, is defined only when each stratum has exactly two PSUs. A stratum with one PSU can be merged with another such stratum, or can be split to appear in both half samples with half weight. The latter approach is appropriate for a PSU that was deterministically sampled.
BRR方差估计各阶层被分为两，给半样本。平衡需要复制的权重，其中在两个不同阶层的观测最终在同一半分层尽可能经常在strata.BRR不同的半，严格地说，只有当被定义每个层具有恰好两个PSU。与一个PSU层数可以与另一个这样的阶层合并，或可以被分割以出现在两个半样品的一半重量。后一种方法是适合的电源供应器，确定的采样。
A stratum with more than two PSUs can be split into multiple smaller strata each with two PSUs or the PSUs can be merged to give two superclusters within the stratum.
层数两个以上的事业单位，可以分割成多个更小的阶层，每两个电源或合并的事业单位可以给两个超星系团内的地层。
When merging small strata or grouping PSUs in large strata the match variable is used to sort PSUs before merging, to give approximate matching on this variable.
当合并小层或分组事业单位，在大型地层match变量是用来排序的事业单位合并前，给这个变量的近似匹配。
If you want more control than this you should probably construct your own weights using the Hadamard matrices produced by hadamard
如果你想更多的控制权，你应该构建自己的重量，使用Hadamard矩阵产生的hadamard
