Regroup the dates

• 

Recall : The transformation Regroup the dates is possible for the date variables.

This assistant allows to regroup the dates by category/class. For example, we can decide to regroup all our dates by years.

You have two possibilities :

• Either to regroup the dates in predefined periods, type month/year, trimester, semester etc.
• Or to regroup the dates in personalized periods, to be entered manually ( type DD.MM.YYYY, for example « 01.02.2003 ; 01.02.2004 ; 01.02.2005 » will create four periods, before 01.02.2003 ; between 01.02.2003 and 01.02.2004 ; between 01.02.2004 and 01.02.2005 and finally after 01.02.2005)

 

3 Choose if you wish to modify the variable chosen by recoding it (you will lose the initial variable) or if you want to create a new variable.

4 In the case of the creation of a new variable, inform at minimum the name of this variable and possibly the title,

5 Then choose the location of the insertion of the new variable created (after the variable selected or at the end of the questionnaire).
