Survival Analysis of Interval-Censored Event-Time Data in Stata — Professional Development Computer Technology Workshop
ASA, StataCorp
This workshop covers the use of Stata to perform survival analysis of interval-censored event-time data. In survival analysis, interval censoring occurs when the event time is not exactly observed but is only known to lie within some time interval. Survival data that contain a mixture of uncensored, right-censored, left-censored, and interval-censored observations are called interval-censored event-time data, and these data arise in many areas, including medical, epidemiological, economic, financial, and sociological studies. Ignoring interval-censoring will often lead to biased estimates. The course will provide a brief introduction to interval-censored data and will demonstrate how to fit parametric survival models and the semiparametric Cox model for interval-censored data in Stata. How to interpret results and plot the survivor function will be discussed with accompanying examples. Also, a number of examples demonstrating how to graphically evaluate goodness of fit and how to graphically check the proportional-hazards assumption will also be presented. No prior knowledge of Stata is required, but basic familiarity with survival analysis will prove useful.
