kaplan-meier

So I have somehow got involved in a forecasting project at work and am currently making things up as I go along (because no one else has any clue what they're doing either), but would greatly value your input as to the best method of approach. Scenario: Insurance policies are sold with an...

Hi all, I'm creating Kaplan-Meier plots with ggsurvplot on weighted data. When I add the risk.table (showing the number at risk over time) I get long decimals because of the weighted data. Is there a way to round the number at risk in the risk.table? I've tried overriding the ggrisktable...

Suppose that n individuals have lifetimes represented by random variables T_1, T_2, \ldots, T_n. Instead of the observed values for each lifetime, we have a time t_i' which we know is either the lifetime or censoring time. Let us define a variable \delta_i=I(T_i=t_i') that equals 1 if...

This may be a stupid question, but: can you construct Kaplan-Meier curves for repeat event data? Or should I limit each individual to occurrence of the first event? Thanks so much everyone! -Laura

Hello, I have a question about what we call "incidence rate" at the end of a longitudinal study. If there are a number of censored data, how do you calculate this IR. Is that the same calculation as Kaplan Meir estimate at the end of the study, or there is another way to calculate it...

Hi all, My colleagues and I are working on a project (i.e., health economics model) where we have fitted parametric curves (using Weibull, Exponential, Gompertz, Log-logistic, Log-normal, and Gamma distributions) to Kaplan-Meier data. In the project, we have estimated various survival curves...

Hi all, So first off, I am a novice so I apologize if this is a beginner question. I am doing a research project where I am looking at immune sensitization prior to heart transplants and seeing if it has any bearing on outcomes after transplant. Patients fall into either a "Hi" or a "Lo"...

Hi, I'm trying to compare two Kaplan Meier survival curves in SPSS. It's about the overall survival between two groups. Now I've entered the months (as time), the status (0=censored, 1=deceased) and I put my variable 'group' into the factor box. But then, when I analyze, it doesn't show...

hi everyone! thanks in advance for your help! i'm studying whether the presence of high v. low hormone levels (of several different hormones) affects survival - i assume that i am to use kaplan-meier to analyze the data rather than cox regression. i am also not sure how to get SPSS to...

Hi all, I need to predict 5 year survival proportion with a kaplan meier plot. Thus far, I'm getting mean and median survival times. How do I get what I need? Thank-you very much.

Hi, I've conducted a kaplan-meier survival plot relating the event (death), to time (varying follow-up times around 2 years). The output has shown me a mean, and median survival time with confidence intervals. I'd like to represent my findings as "expected" survival at 1 and 5 years. How...
