• Functions
  • I do remember giving a talk in my Biostats school about playing Russian roulette by varying the number of bullets over a series of plays to represent various hazard (individual and group) functions we were entertaining in modeling survival data. (andrewgelman.com)
  • Estimators
  • He was a distinguished mathematical statistician whose wide-ranging research included the analysis of martingale inequalities, Markov processes, de Finetti's theorem, consistency of Bayes estimators, sampling, the bootstrap, and procedures for testing and evaluating models. (wikipedia.org)
  • Methods
  • This volume is an accessible, data-based introduction to methods of survival analysis. (alibris.com)
  • Each included study may be assigned an objective assessment of methodological quality preferably by using methods conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement (the current guideline) or the high quality standards of Cochrane. (wikipedia.org)
  • Times
  • The children who had palliative surgery had longer survival times than those who had corrective surgeries. (redorbit.com)
  • Models
  • Optimum predictions are derived for familiar survival models and the accuracy of these predictions is investigated. (lancs.ac.uk)
  • clinical
  • The purpose of this study was to investigate the relationship between survival time after mastectomy and a number of clinical and morphological variables. (scielo.br)
  • Death
  • In the case of biological survival, death is unambiguous, but for mechanical reliability, failure may not be well-defined, for there may well be mechanical systems in which failure is partial, a matter of degree, or not otherwise localized in time. (wikipedia.org)
  • in this context, death or failure is considered an "event" in the survival analysis literature - traditionally only a single event occurs for each subject, after which the organism or mechanism is dead or broken. (wikipedia.org)
  • disease
  • For instance, a highly toxic treatment with number of side effects might delay disease recurrence and increase the survival relative to a less toxic treatment. (expertsmind.com)
  • cause specific survival has the advantage that it does not depend on the ability to find a similar population of people without the disease. (wikipedia.org)
  • These include the disease-free survival (DFS) (the period after curative treatment [disease eliminated] when no disease can be detected), the progression-free survival (PFS) (the period after treatment when disease [which could not be eliminated] remains stable, that is, does not progress), and the metastasis-free survival (MFS) or distant metastasis-free survival (DMFS) (the period until metastasis is detected). (wikipedia.org)
  • mean
  • Mean-range plot is the graphical tool or device useful in selecting a transformation in the time series analysis. (expertsmind.com)
  • Note that in statements of the assumptions underlying regression analyses such as ordinary least squares, the phrase "no multicollinearity" is sometimes used to mean the absence of perfect multicollinearity, which is an exact (non-stochastic) linear relation among the regressors. (wikipedia.org)
  • literature
  • I believe one of the best things in my career development is that I first encountered the scientific process - critically - the analysis of literature, art and culture (i.e. anthropology). (andrewgelman.com)
  • Long term survival is currently even more promising, although this impression is not reflected in the recent literature. (wikipedia.org)
