    gbm: Generalized Boosted Regression Models Cox proportional hazards partial likelihood, AdaBoost exponential Depends: R (≥ ). Generalized Boosted Regression Models. An implementation of extensions to Freund and Schapire's AdaBoost algorithm and Friedman's gradient boosting machine. The gbm package (which stands for generalized boosted models) implements extensions to Freund and Schapire’s AdaBoost.
    I am so sorry for not allowing to add picture which illustrates the equation.

    So you might have to go to the source code and make your own function to extract or reconstruct what you need to mimic plot survfit.

    Related 1. The best answers are voted up and rise to the top. See also the hidden helper function reconstructGBMdata. What does it do? When you use exp fitted values you are "back transforming" the regression fit to get relative risks, since you used a log link when doing Poisson regression.

    Thank you for your reply.

Actually, the returns is cumulative baseline hazard function(integral part: \int^t\ lambda(z)dz), and survival function can be computed as below.

    On the other hand, as my data is a kind of cohort, I have a trouble understanding the result of this model.

    I am looking for a way to impute a training set and use the same imputation on test data.

    I also wanted to comment on using gradient boosting models, specifically for handling missing values.
