Facilities provided by missing values processing
Missing values processing is an optional feature. If you use it, Quantum automatically detects missing values and provides a variety of facilities for dealing with them in both the edit and tabulation sections of your run. In the edit section you have:
▪Automatic replacement of missing values with the special value missing_.
▪An ismissing function to check whether a variable has the special value.
▪Manual assignment of the special value missing_ to variables of your choice within the edit.
