Where do I define missing values?

Missing values can be defined in DataLion. Thus, it can also be decided how to deal with missing values (include or exclude).

In the backend it must be specified which values are defined as missing values. The corresponding field can be found under Projects -> Selection of the corresponding project

--> in the "Data" tab

The missing values can be listed separately with a comma (,).

In addition, 0 values and empty data are predefined as missing values. This selection can be deactivated with a click:

See example:

Under "NA handling" you can define how the missing values should be processed (include or exclude them).
