TSINFO Procedure

The TSINFO procedure evaluates a variable in an input data table for its suitability as a time ID variable in SAS procedures and solutions that are used for time series analysis. PROC TSINFO assesses how well a time interval specification fits SAS date values, SAS datetime values, or observation numbers that are used to index a time series. The time interval used in this analysis can be either specified explicitly as input or inferred based on values of the time ID variable. The TSINFO procedure produces diagnostic information in the form of data tables and ODS tables. These diagnostic results summarize characteristics of the time ID variable that can help determine its use as an index in other time series procedures and solutions.

PROC TSINFO is intended for use as a tool to either identify the time interval of a variable or prepare problematic data sets for use in subsequent time series analyses. In particular, this procedure can be used to investigate inconsistencies between time ID values and the ID statement options that are used in other SAS procedures and solutions.
