- Abstract
This paper discusses the benefits of using SPlus software to carry out longitudinal analyses such as event history methods. An illustration is provided using three-year career histories of a nationally drawn cohort of recently qualified registered nurses, who completed a diploma programme in the UK between August 1997 and September 1998. For the purposes of this paper, the time to first promotion is examined using a Cox proportional hazards model with a frailty term included, to allow for unobserved heterogeneity. The results indicated that men have a slightly higher rate of promotion compared with women, and particularly when compared with women who took a maternity break during their early career. Age is also a significant factor, with younger cohort members being promoted at a higher rate than their older colleagues. The inclusion of a frailty term to account for clustering at the university level also significantly improved the model. It is shown that SPlus, which is a powerful, user-friendly statistical package, can be easily utilized by researchers to carry out event history analysis as well produce high quality cumulative hazard and diagnostic plots using its sophisticated graphics facilities.
