On the expected discounted penalty function associated with the time of ruin for a risk model with random

具有随机保费的风险模型下的平均折现罚金函数，汪荣明，姚定俊，本文考虑随机保费的风险模型下平均折现罚金函数。与经典的风险模型相比较保费过程不再是线性过程，总保费过程构成一复合Poisson过�

此处指的是XGBoost、LightGBM或H2O中predict()函数所需的数据集格式。对于XGBoost，输入参数应为一个矩阵或xgb.DMatrix对象；对于LightGBM，输入参数应为一个矩阵；对于H2O，输入参数应为一个data.frame或H2OFrame对象。此参数仅适用于XGBoost、LightGBM或H2O对象。
