Overview
RMV NEWVAR1=LINT(OLDVAR1).
RMV produces new variables by copying existing variables and replacing any system- or
user-missing values with estimates computed by one of several methods. You can also use
RMV to replace the values of existing variables. The estimated values are computed from
valid data in the existing variables. The new or revised variables can be used in any procedure
and can be saved in an SPSS-format data file.
Basic Specification
The basic specification is one or more new variable names, an equals sign, a function, and
an equal number of existing variables. RMV displays a list of the new variables, the number
of missing values replaced, the case numbers of the first and last nonmissing cases, the
number of valid cases, and the function used to produce the variables.
Syntax Rules
• The existing variables (and span, if specified) must be enclosed in parentheses.
• The equals sign is required.
• You can specify more than one equation on RMV.
