is the cost and p is the risk. As p increases, the risk is increasing but
the cost is decreasing. The question is how to minimize the cost and keep
the risk not too high? Thanks! | T*******I

篇用最优化分割的思想找疾病控制中的单位成本临界点的文章。与你的这个问题极其相
似。但我不知道你的问题究竟是属于纯数学函数领域的问题还是统计学中的回归模型的
问题。我的问题属于统计学中的分段回归。建议你去查查这篇文献。我手里没有了。

是风险权重一点还是成本权重一点。 | c*******1
