Survey design

This module is still under development. Some features of iNZight lite will not work when it is used. Every design specified is connected to the data set selected at the time the design was created. Make sure the right data is selected first. If the data set is changed the design is deleted and needs to be recreated. The survey design module adds or removes a survey design design to the vizualize modules plotting functionality. To use this module a survey data set should be loaded. There are four dropdown menues and one check box. - strata The first dropdown menu specifies the strata. Select a variable from the list. - clustering The second dropdown menu specifies the clustering variable or id variable in the survey design function (svydesign) More than one variable can be selected. The "none" variable which is selected as default is removed from the selection internaly and can be ignored. All selected variables are pased into the "svydesign" function as formula. The format is "~var1 + var2 + ...". - weighting The weighting variable is the third variable. Please specify on what variable the survey design is weighted. - nest Whether it is a nested design or not can be specified with this check box. - fpc The finite population correction variables are selected with the last dropdown menu. As in clustering more than one variable can be selected. In fact the number of variables selected for fpc should equal the number of variables selected in clustering. For more information please look at the R survey package.
