Create Time Series

The Create Time Series dialog box allows you to create new variables based on

functions of existing numeric time series variables. These transformed values are

useful in ma

ny time series analysis procedures.

Default new variable names are the first six characters of the existing variable used

to create it, followed by an underscore and a sequential number. For example, for the

variable pr

ice, the new variable name would be price_1. The new variables retain

any defined value labels from the original variables.

Available functions for creating time series variables include differences, moving

averages,

running medians, lag, and lead functions.
