Select an option to handle missing data:
Fail If any missing values are encountered, the procedure fails with an error.
Omit Cases with NAs in any of the variables to be crosstabulated are omitted from the crosstabulation.
Include The level NA is added to each factor before the crosstabulation is performed.
It is also possible to enter a user-defined function here. If there are any missing values in the data to be crosstabulated, the data are put into a data set and passed to this function.
If a data set is open and active, then by default this data set is used in the crosstabulation. If some of its columns are highlighted, then by default these columns are used in the crosstabulation. If none of its columns are highlighted, then by default all of its columns are used in the crosstabulation.
