Introduction to Survival Analysis, type of problem addressed by survival analysis, the outcome variable considered, the need to take into account “censored data,” what a survival function and a hazard function represent, basic data layouts for a survival analysis, the goals of survival analysis, and some examples of survival analysis.作者: 愉快嗎 時(shí)間: 2025-3-22 05:26 作者: Excise 時(shí)間: 2025-3-22 12:35 作者: 離開(kāi)真充足 時(shí)間: 2025-3-22 13:31 作者: 大門在匯總 時(shí)間: 2025-3-22 17:33
Evaluating the Proportional Hazards Assumption,We begin with a brief review of the characteristics of the Cox proportional hazards (PH) model. We then give an overview of three methods for checking the PH assumption: graphical, goodness-of-fit (GOF), and time-dependent variable approaches.作者: GRILL 時(shí)間: 2025-3-23 00:55
The Stratified Cox Procedure,We begin with an example of the use of the stratified Cox procedure for a single predictor that does not satisfy the PH assumption. We then describe the general approach for fitting a stratified Cox model, including the form of the (partial) likelihood function used to estimate model parameters.作者: EXCEL 時(shí)間: 2025-3-23 04:19
Extension of the Cox Proportional Hazards Model for Time-Dependent Variables,We begin by defining a time-dependent variable and providing some examples of such a variable. We also state the general formula for a Cox model that is extended to allow time dependent variables, followed by a discussion of the characteristics of this model, including a description of the hazard ratio.作者: Pillory 時(shí)間: 2025-3-23 06:10 作者: Tartar 時(shí)間: 2025-3-23 10:24 作者: 遷移 時(shí)間: 2025-3-23 16:03 作者: Debark 時(shí)間: 2025-3-23 21:35
Parametric Survival Models, parametric likelihood is constructed and described in relation to left, right, and interval-censored data. Binary regression is presented as an alternative approach for modeling interval-censored outcomes. The chapter concludes with a discussion of frailty models.作者: 焦慮 時(shí)間: 2025-3-23 23:19

Parametric Survival Models,s of survival models, called parametric models, in which the distribution of the outcome (i.e., the time to event) is specified in terms of unknown parameters. Many parametric models are acceleration failure time models in which survival time is modeled as a function of predictor variables. We exami作者: archenemy 時(shí)間: 2025-3-24 12:21
Recurrent Event Survival Analysis,nts.” Modeling this type of data can be carried out using a Cox PH model with the data layout constructed so that each subject has a line of data corresponding to each recurrent event. A variation of this approach uses a stratified Cox PH model, which stratifies on the order in which recurrent event作者: 連鎖,連串 時(shí)間: 2025-3-24 16:08
Competing Risks Survival Analysis, contrasts with the topic of the preceding chapter in which subjects could experience more than one event of a given type. When only one of several different types of event can occur, we refer to the probabilities of these events as “competing risks,” which explains the title of this chapter.作者: 露天歷史劇 時(shí)間: 2025-3-24 21:46 作者: jocular 時(shí)間: 2025-3-25 01:04

Recurrent Event Survival Analysis,orrelation among recurrent events on the same subject. Such adjusted variance estimates are called “robust variance estimates.” A parametric approach for analyzing recurrent event data that includes a frailty component (introduced in Chapter 7) is also described and illustrated.作者: 思考才皺眉 時(shí)間: 2025-3-25 11:30 作者: Root494 時(shí)間: 2025-3-25 13:43
