This is a sample replication dialog box--this one for the replicated descriptive statistics.  Dependent and independent variables are specified in the usual manner.  If an overall weight is used, it goes in the edit box labeled "weight."  Replicate weights are dragged into the "replicate weights" box.  If default replicate weights are specified, they will appear in the box automatically.

The user must specify the replication method.  It is important that you correctly identify the replication method for which the weights were developed, or the estimates will not be correct.   

Jackknife 2 (JK2) may be the most common method, which is employed when the sample was explicitly stratified.  JK1 uses a slightly different reweighting factor and is typically used when the sample was not explicitly stratified.  Estimates for these two methods tend to be very similar, so it will not be immediately apparent if the wrong method is specified.  Balanced Repeated Replication estimates are much smaller than the jackknife estimates, so you've used BRR and the standard error numbers are unreasonably small your weights were probably developed for a jackknife procedure.  Similarly, if you've selected a jackknife procedure and your standard errors are unreasonably large, the weights were probably developed for BRR.  Fay's method is a variant of the BRR.

If you select Fay's method (which you should only do if your weights were developed for Fay's method) you will have to supply an additional piece of information--the re-weighting factor (a number between 0 and 1 that represents the adjustment to the weights of each half sample).

When you select Fay's method, an edit box will appear that will allow you to enter the constant:
