You can perform weighted calculations in DataTile, assuming that the database contains weight variables. When loaded from scratch, weights are numerical variables that hold projection factors for each respondent.
After uploading a database, it's essential to declare weight variables as such.
How to declare a numeric variable as a weight
-
Go to the Project settings → Meta-Editor.
-
Locate the variable and click the circle badge on the right.
-
From the pop-up menu, choose ‘Weight factor’.
-
Hide the variable by clicking on the eye icon on the left, because it won’t be needed for the analysis as a plain numeric variable.
Repeat this process for the other weighting variables.
Weights settings
Having declared weights in the database, you can further enhance the user experience.
Go to Project settings → Settings → Weights
-
Default weighting: to define the default weight to apply to new runs.
-
Hide the weighting switcher from the user interface and apply weight implicitly: This tick hides the weighting switcher from the user interface, enforcing the default weight to be used for all runs under the hood.
-
Force weighting of sample metrics: This weight will be applied to all sample metrics, disregarding the user-selected weight.
-
Forbid unweighted calculations: If this option is selected, users can switch weights, but untoggling the weighting switcher is forbidden.
-
A dataset may contain multiple weights, but only some of them are relevant for the target audiences. You can disable irrelevant weights at the dataset or Data View level without changing the variable type. Open the dropdown list and click the ‘eye’ icon to manage their visibility. Disabled weights cannot be selected for calculations or set as the default weight.
