Survival data with time-varying covariates are common in practice. If relevant, they can improve on the estimation of a survival function. However, the traditional survival forests-conditional inference forest, relative risk forest and random survival forest-have accommodated only time-invariant covariates. We generalize the conditional inference and relative risk forests to allow time-varying covariates. We also propose a general framework for estimation of a survival function in the presence…

Relative risk trees for censored survival data.
A method is developed for obtaining tree-structured relative risk estimates for censored survival data using a recursive partitioning algorithm that adopts most aspects of the widely used Classification and Regression Tree (CART) algorithm.
Survival trees for left‐truncated and right‐censored data, with application to time‐varying covariate data
This work proposes two new survival trees for left‐truncated and right‐censored (LTRC) data, which can be seen as a generalization of the traditional survival tree for right-censored data and shows that such trees can be used to analyze survival data with time‐varying covariates, essentially building a time-varyed covariates survival tree.
Estimating the causal effects of multiple intermittent treatments with application to COVID-19
A joint marginal structural proportional hazards model and novel weighting schemes in continuous time to account for time-varying confounding and censoring are developed and applied to a large-scale CO VID-19 dataset to estimate the causal effects of several COVID-19 treatment strategies on in-hospital mortality or ICU admission.
Predictive Distribution Modeling Using Transformation Forests
A novel approach based on a parametric family of distributions characterized by their transformation function is proposed, which introduces “transformation forests” as an adaptive local likelihood estimator of conditional distribution functions.
Dynamic estimation with random forests for discrete‐time survival data
Time‐varying covariates are often available in survival studies, and estimation of the hazard function needs to be updated as new information becomes available. In this article, we investigate

Discrete-time survival forests with Hellinger distance decision trees
A RSF algorithm specifically designed for the analysis of (possibly right-censored) discrete event times is developed based on an ensemble of discrete-time survival trees that operate on transformed versions of the original time-to-event data using tree methods for binary classification that implements a node splitting strategy based on Hellinger’s distance.
Clinical risk prediction with random forests for survival, longitudinal, and multivariate (RF-SLAM) data analysis
RF-SLAM is a novel statistical and machine learning method that improves risk prediction by incorporating time-varying information and accommodating a large number of predictors, their interactions, and missing values, and demonstrates superior performance relative to standard random forest methods for survival data.
Tree-based modeling of time-varying coefficients in discrete time-to-event models
A tree-based method is proposed for modeling the piecewise constant time-varying coefficients, which is embedded into the framework of varying-coefficient models and its usefulness is demonstrated by considering two real-world applications.
Survival Trees by Goodness of Split
Abstract A tree-based method for censored survival data is developed, based on maximizing the difference in survival between groups of patients represented by nodes in a binary tree. The method
