Optimal survival trees ensemble
… notion, the possibility of selecting optimal survival trees is considered in this work. Initially, a large set of survival trees are grown by the method of random survival forest. Using out-of-bag observations for each corresponding survival tree, the trees grown are ranked in ascending order …

Oxidative stress and seed survival
Free radical and aldehydic breakdown product content were determined, by EPR and UV / visible spectroscopy, primarily in intermediate (desiccation tolerant) seeds of <i>Carica papaya</i> L. (Papaya) and recalcitrant (desiccation intolerant) seeds of <i>Aesculus hippocastanum</i> L. (Horse …

Survival guide for dense networks
High density affects the communication in an energy-constrained network since the energy-saving protocols are not designed to cope with the high contention expected in dense networks. While increased delay and reduced throughput are predictable results of contention from background traffic, high …

Quantile regression and survival analysis
… and focus on two topics: quantile regression and survival analysis. Firstly, direct use of regression quantiles to construct confidence intervals and confidence bands for conditional quantiles and prediction intervals for future response variables under homoscedastic linear models and …

Variable selection in discrete survival models
… model. However, variable selection for discrete survival analysis poses many challenges due to a complicated data structure. Survival data might have unobserved heterogeneity leading to biased estimates when not taken into account. Conventional variable selection methods have stability problems. …

Understanding Cancer Treatment Delay and Survival
… is important for patient disease management and survival among patients with cancer. Guidance for conducting studies examining the association between the DTI and overall survival (OS) is needed to address potential bias, improve methodological rigor, and ensure readily comparable results. …

Personal Identity, Survival And What Matters
<p>Since the entire discussion of personal identity revolves around the identity of a person it is difficult to address these issues without presupposing that identity is maintained. In this dissertation, I propose an alternative approach to discussing the topic of personal identity (at least …

Alternative estimation methods for survival models
… the parameters of two types of three parameter survival models for the force of mortality, the Makeham model and the Weibull model. The existing methods for estimating these parameters by the method of least-squares include using a log-transformation on the force of mortality data. We will …

Nuisance Parameter Estimation in Survival Models
… However, both alternatives require a conditional survival function as a nuisance parameter. This thesis focuses on the impact of the conditional survival function on the estimation of censored quantile regression and restricted means. In particular, we illustrate that a non-parametric estimator of …

Hierarchical modelling of multivariate survival data
… as a means of modelling multivariate survival times. The model structure follows Clayton (1978), Hougaard (1986b), and Oakes (1986, 1989). Both approximate Bayesian and maximum likelihood estimation in these models is investigated via simulation. Predicting a component of a response …

Fierce: Black Queer Literacies of Survival
<p>Influenced by Black feminist and queer scholars, my dissertation focuses on how Black and queer people have made interventions through language and performance to survive larger racist and homophobic forces. Despite critical scholarship on the literacies of both Black and queer communities, …
