Nonparametric priors for vector of survival functions [PDF]

, 2008
The paper proposes a new nonparametric prior for two-dimensional vectors of survival functions . The definition is based on the Lévy copula and it is used to model, in a nonparametric Bayesian framework, two-sample survival data. Such an application yields a natural extension of the more familiar neutral to the right process of Doksum (1974) adopted ...

The alpha-mixture of survival functions

Journal of Applied Probability, 2019
AbstractThis paper presents a flexible family which we call the $\alpha$ -mixture of survival functions. This family includes the survival mixture, failure rate mixture, models that are stochastically closer to each of these conventional mixtures, and many other models. The $\alpha$ -mixture is endowed by the stochastic order and uniquely possesses a

Cognitive functioning predicts survival in the elderly

Journal of Clinical and Experimental Neuropsychology, 2008
Prior studies of aging have identified a number of predictors of survival, including performances on some cognitive-functioning tests. However, few studies have used a multidomain test battery to identify which specific cognitive abilities predict death.

Medulloblastoma in childhood. Survival and functional results

Acta Neurochirurgica, 1979
The authors report on a series of 57 medulloblastomas in children operated upon -etween 1964 and 1976. Among these children, 44 completed the treatment with radiotherapy to the whole central nervous system. The postoperative mortality rate in 10.5%. Postoperative deaths occurred mainly in infants or when a tumour involved the brain stem.

Product-limit survival functions with correlated survival times

Lifetime Data Analysis, 1995
A simple variance estimator for product-limit survival functions is demonstrated for survival times with nested errors. Such data arise whenever survival times are observed within clusters of related observations. Greenwood's formula, which assumes independent observations, is not appropriate in this situation.

Variance estimation of a survival function for interval‐censored survival data

Statistics in Medicine, 2001
AbstractInterval‐censored survival data often occur in medical studies, especially in clinical trials. In this case, many authors have considered estimation of a survival function. There is, however, relatively little discussion on estimating the variance of estimated survival functions. For right‐censored data, a special case of interval‐censored data,

Cognitive functioning and survival in psychogeriatric patients

Acta Psychiatrica Scandinavica, 1991
The relationship between cognitive functioning and survival was studied among 92 people referred to a psychogeriatric assessment unit. A follow‐up 4–5 years later showed that the nonsurvivors initially had lower scores on the Mini‐Mental State Examination (MMSE) than the survivors.
