Hi

in the method TreeSurvival::computePredictionAccuracyInternal(), Visual Studio give a warning on the line:

sum_chf.push_back(std::accumulate(chf[terminal_nodeID].begin(), chf[terminal_nodeID].end(), 0));

because the last argument is a integer. So the result of this accumulation is trunk to an integer.
If the expected result must not be trunked, the line must be

sum_chf.push_back(std::accumulate(chf[terminal_nodeID].begin(), chf[terminal_nodeID].end(), 0.0));

Best regards

Remi
