Combine variables

• 

This assistant allows to create a new variable from a combination of several variables chosen. To get access to this assistant, proceed as follows :

• From the tab Data, click Combine

You reach a dialog box where you can select a type of combination of variables among the first four propositions :

• Create a variable from a sub-sample : allows you to create a closed variable which modalities correspond to conditions fixed by the user (sub-sample or profile). Therefore the already defined sub-samples appear. The new closed variable is defined by the modalities selected from the sub-samples, if necessary we create a new profile to create another modality.
• Merge several closed variables : Several types of fusion will then be proposed :
  - Simple fusion : The modalities of the new multiple closed variable are all those of the variables selected.
  - Composed fusion : The modalities of the new multiple closed variable are the different modalities of the variables selected.
  - Cross fusion : The modalities of the new uinque closed variable cross the modalitites of the variables selected.
  - Multiple fusion :The modalities of the new multiple closed variable are the names of the variables selected.
• Transpose several closed variables : Create a set of variables having the modalities of the variables selected as name.
• Concatenate the texts of the responses  : Create a text variable which gathers the contents of the responses of the variables selected.

All these combinations are detailed below in the section Operating modes.
