Abstract

This research aimed to (1) estimate the survival functions, and (2) investigate the effect of some covariates toward the survival time  from hospitalization time data in Public Health Center of Indralaya. The research subjects consisted of all the diarrhea patients who were hospitalized within the period from January 1, 2014 to June 30, 2014. The patient's characteristics were sex, age, job, and disease status. The result showed that the lowest probability of a patient will be out of hospitalization was on the fourth day and the highest probability was on the fifteenth day. In order to find the best model, some statistical tests were also conducted in this research.

Abstract

In this study, we aimed to (1) show whether the Sriwijaya University tracer study data follow some survival distributions,  (2)  find the best survival distribution to represent the data, and (3) estimate the survival probability and hazard rate of the data. The tracer study was conducted from January 1, 2012 to December 31, 2012. There were 637 alumni who participated in the study. The result showed that the data follow the normal distribution, logistic distribution, and SEV distribution, in which the normal distribution was the best in representing the data. Based on the estimation procedure, the lowest probability of finding the first job was before graduation and the highest probability was about two years after graduation.
