The TIMEID Procedure

The TIMEID procedure evaluates a variable in an input data set for its suitability as a time ID
variable in SAS procedures and solutions that are used for time series analysis. PROC TIMEID
assesses how well a time interval specification fits SAS date or datetime values, or observation
numbers used to index a time series. The time interval used in this analysis can be either specified
explicitly as input to PROC TIMEID or inferred by the procedure based on values of the time ID
variable. The TIMEID procedure produces diagnostic information in the form of data sets and ODS
tabular and plotted output. 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 TIMEID 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 used in other SAS procedures and solutions.
