The R package ‘survivalPLANN’ contains a variety of functions to estimate a survival neural network. The Partial Logistic Artificial Neural Networks (PLANN) are implemented, proposed by Biganzoli et al. (1998). S3 methods are included to evaluate the predictive capacities, as well as predictiions from new observations.

dnew <- data.frame(sex=c(1,2), delay=c(0,0), stade=c(0,0))

# Predictions for a men or a women with no delay at the diagnostic of non-agressive cancer
