In R, what is the best way to incorporate the interaction term between a covariate and time, when the proportionality test (with coxph) shows that the proportionality assumption in the Cox model is...

Is there an easy way to generate a swimmer plot in R? Same data as in a KM curve but with each individual survival represented as a line. Example: I've searched stackoverflow, the R-help mailing...

Argh! I keep getting the following error when attempting to compute with my neural network: > net.compute <- compute(net, matrix.train2) Error in neurons[[i]] %*% weights[[i]] : non-conforma...

I have the following risk table for a Kaplan Meier curve constructed with surv_miner in RStudio: Kaplan Meier curve I would like to string wrap the text in the risk table so that the number is on...

I'm confused how to interpret the output of .predict from a fitted CoxnetSurvivalAnalysis model in scikit-survival. I've read through the notebook Intro to Survival Analysis in scikit-survival and ...

I want to perform survival analysis (Kaplan-Meier and Cox PH modelling) on data which is both left and right censored. I'm looking at the time to occurrence of a heart arrhythmia (AF) in the presen...

there is quite a lot of information (internet and textbooks) on how to do survival analysis in R with the survival package. But I don't find any information on how to do this when you have left cen...

I would like to implement diagnostics for Cox proportional hazards model with ggplot2, by creating new stats functions and ggproto objects. The idea is to benefit from grouping (by color, facet_gri...

I'm trying to run a survival analysis in R using the survival package. I have right-censored data only (time to event, then event "1" or censor "0"). I created a survival object using the Surv func...

My doubt is if it is possible to pool multiple imputation data set, from "mice()", on a fit model of Fine-Gray from "crr()", and if it is statistically correct... example librar...

I have a modeled a problem using Cox's regression and now want to predict the estimated survival time for an individual. The model has a list of covariates on which the survival time depends. This ...

I am trying to find a way to model Survival Models for Recurrent Events in Python, especially the Counting process approach using CoxPH. In Counting Process Approach, it is expecting start-time and...

I have binned data I'm trying to perform a survival analysis on, example data below. n is a count of units at each group, time, failure indicator combination. > df <- structure(list(group = ...

I am puzzled at a behaviour of a function that I am trying to write. My example comes from the survival package but I think that the question is more general than that. Basically, the following cod...

I am currently working on a meta-analysis of survival data across several clinical trials. To do this, I have code from a published analysis using the same methodology. However, when running this ...

I tried to port simple survival model from here (the first one in introduction) form PyMC 2 to PyMC 3. However, I didn't find any equivalent to "observed" decorator and my attempt to write a new di...

I'm using rfsrc to model a survival problem, like this: library(OIsurv) library(survival) library(randomForestSRC) data(burn) attach(burn) library(randomForestSRC) fit <- rfsrc(Surv(T1, D1) ...

The muhaz package estimates the hazard function from right censored data using kernel smoothing methods. My question is, is there any way to obtain confidence intervals for the hazard functio...

I've been looking for a solution to plot survival curves using ggplot2. I've found some nice examples, but they do not follow the whole ggplot2 aesthetics (mainly regarding shaded confidence interv...

I have data called veteran stored in R. I created a survival model and now wish to predict survival probability predictions. For example, what is the probability that a patient with 80 karno value,...

I am new to survival analysis and survfit in R. I want to extract survival probabilities for 4 groups (diseases) at specified time periods (0,10,20,30 years since diagnosis) in a table. Here is the...

I want to compute the AIC value for my survival analysis objects (suvfit/coxph). When I try to do it, it says: > AIC(cox) Error in UseMethod("logLik") : no applicable method for 'logLik' app...

Hi I am totally new to R. This is my first attempt at it. I am producing a survival plot broken down by age. I can't figure out how to specify colours for each age line and put it in a legend. Can ...

I'm trying to use the R survival package, to produce a plot of log(-log(survival)) against log(time) (This is something sometimes recommended as a way to visually inspect for accelerated lifetime ...

I'm having some trouble using coxph(). I've two categorical variables:"tecnologia" and "pais", and I want to evaluate the possible interaction effect of "pais" on "tecnologia"."tecnologia" is a var...
