KM LENGTH BY SEXRACE
/STATUS=EMPLOY EVENT (1) LOST (2)
/STRATA=LOCATION.
- Survival analysis is used to examine the length of
unemployment. The survival variable LENGTH contains the number of months a subject is unemployed. The factor
variable SEXRACE combines sex and
race factors.
- A value of 1 on the variable EMPLOY indicates the occurrence of the event (employment).
All other observed cases are censored. A value of 2 on EMPLOY indicates cases lost to follow-up.
Cases with other values for EMPLOY are known to have remained unemployed during the course of the study.
KM separates the two types of censored cases
in the KM table if LOST is specified.
- For each combination of SEXRACE and LOCATION, one KM table is
produced, followed by the mean and median survival times with standard
errors and confidence intervals.
