New TIMEID Procedure

The new TIMEID procedure analyzes the sequence of ID values in a SAS data set to identify the time interval between observations and verifies that the observations in the data set represent a properly spaced time series.

The TIMEID procedure provides the following features:

• Specified time intervals and alignments can be used to evaluate a data set’s time ID values in terms of the distributions of duplicated values, alignment offsets, and the gaps between adjacent observations.

• The time interval’s width, shift, and alignment can be inferred from a time ID variable. When either the interval or its alignment is specified, this information is used to guide the process of inferring the remaining quantity.

• When multiple BY groups are present, detailed diagnostics for each BY group are reported in addition to summarized diagnostic information which applies to all BY groups in the data set.
