Analysis Preparation Wizard, Size step
This step is used to specify inclusionprobabilities or population sizes for the current stage. Sizes
can be fixed or can vary across strata. For the purpose of specifying sizes, clusters specified in
previous stages can be used to define strata. Note that this step is necessary only when Equal
WOR is chosen as the Estimation Method.
Units. Youcan specify exact population sizes or the probabilities with which units were sampled.
Value. Asingle value is applied to all strata. If PopulationSizes is selected as the unit metric,
you should enter a non-negative integer. If Inclusion Probabilities is selected, you should enter
avaluebetween 0 and 1, inclusive.
Unequalvalues for strata. Allows you to enter size values on a per-stratumbasis via the Define
Unequal Sizes dialog box.
Readvalues from variable. Allows you to select a numeric variable that contains size values
for strata.
