Thank you for your replies. Apologies for the confusion.

This is quality control data where the goal is for organizations to move up in quality ranking from 1 to 5. Programs can move from 1 to 3 in one step, but most progress one increment at a time. So I believe the scenario is multiple sequential events per organization.

Thank you,

John

Bruce, I once looked into when one has repeated events in the context of a time-to-event analysis/design, and such recurrent events analysis can be analyzed (which I haven't used) via a R package called "Frailtypack", which has the following description from the R website:   "Frailtypack now fits several classes of frailty models using Penalized Likelihood on the hazard function. 1) A shared gamma frailty model and Cox proportional hazards model. Left truncated, censored data and strata (max=2) are allowed. Clustered and recurrent survival times can be studied (the Andersen-Gill(1982) approach has been implemented for recurrent events). An automatic choice of the smoothing parameter is possible using an approximated cross-validation procedure. 2) Additive frailty models for proportional hazards models with two correlated random effects (intercept random effect with random slope). 3) Nested frailty models for hierarchically clustered data (with 2 levels of clustering) by including two iid gamma random effects. 4) Joint frailty models in the context of joint modelling of recurrent events with terminal event."   .......but I haven't used the GENLINMIXED option in SPSS, so maybe it is equipped to do recurrent events analysis.......I think (but I would have to double-check) one may be able to do such analysis in Stata, and I would defer to SAS users on this listserve to see if the same can be done for that software..but as I said, there is definitely a R Package     Dale Glaser, Ph.D.Principal--Glaser ConsultingLecturer/Adjunct Faculty--SDSU/USD/Alliant3115 4th AvenueSan Diego, CA 92103phone: [phone]fax: [phone]email: [hidden email]website: www.glaserconsult.com--- On Mon, 9/26/11, Bruce Weaver <[hidden email]> wrote: From: Bruce Weaver <[hidden email]> Subject: Re: multi-event survival analysis? To: [hidden email] Date: Monday, September 26, 2011, 12:53 PM Please clarify what you mean by multiple-event.  I.e., do you mean the sameevent can occur multiple times per person (e.g., time to drink for pts inrehab); or do you mean that there is only one event per person, but an eventis defined as the occurrence of any one of X, Y or Z?  I *think* Rich U wasthinking about the second case when he said Cox regression could do this.For repeated occurrences of the same event, I *think* you'd need to useGENLIN or GENLINMIXED, or something like that.  But there may be others whohave actually done it who can speak with more authority.J P-6 wrote:>> Hello,> Â> Does anyone know if SPSS can handle a multi-event survival analysis?
