Overview
CREATE NEWVAR1 NEWVAR2 = CSUM(TICKETS RNDTRP).
CREATE produces new series as a function of existing series. You can also use CREATE to
replace the values of existing series. The new or revised series can be used in any procedure
and can be saved in an SPSS-format data file.
CREATE displays a list of the new series, the case numbers of the first and last
nonmissing cases, the number of valid cases, and the functions used to create the variables.
Basic Specification
The basic specification is a new series name, an equals sign, a function, and the existing
series, along with any additional specifications needed.
