Rotation survival forest for right censored data
Recently, survival ensembles have found more and more applications in biological and medical research when censored time-to-event data are often confronted. In this research, we investigate the plausibility of extending a rotation forest, originally proposed for classification purpose, to survival analysis. Supported by the proper statistical analysis, we show that rotation survival forests are...
متن کاملRandom rotation survival forest for high dimensional censored data
Recently, rotation forest has been extended to regression and survival analysis problems. However, due to intensive computation incurred by principal component analysis, rotation forest often fails when high-dimensional or big data are confronted. In this study, we extend rotation forest to high dimensional censored time-to-event data analysis by combing random subspace, bagging and rotation fo...
متن کاملUmbrella Tests for Right-censored Survival Data
This paper considers the problem of testing for umbrella alternatives in the one-way layout when survival data are subject to random right censorship. Testing procedures based on two-sample weighted logrank statistics are suggested for both cases when the peak of the umbrella is known or unknown. The Pitman efficacy of the peak-known umbrella test is derived. A class of Lehmann and scale altern...
متن کاملBalanced Random Survival Forests for Extremely Unbalanced, Right Censored Data
Accuracies of survival models for life expectancy prediction as well as lifesaving criticalcare applications are significantly compromised due to the sparsity of samples and extreme imbalance between the survival and mortality classes in addition to the invalidity of the popular proportional hazard assumption. An imbalance in data results in an underestimation (overestimation) of the hazard of ...
متن کاملSpatial Modeling of Censored Survival Data
An important issue in survival data analysis is the identification of risk factors. Some of these factors are identifiable and explainable by presence of some covariates in the Cox proportional hazard model, while the others are unidentifiable or even immeasurable. Spatial correlation of censored survival data is one of these sources that are rarely considered in the literatures. In this paper,...
