中文摘要
当前统计面临的挑战为推进统计理论和方法提供了机会,其特点是复杂的伦理、理论和方法问题。在许多涉及不确定性的实际应用中,统计学习和即时预期收益之间的最佳平衡对于一系列决策的最佳总体性能是可取的。例子包括平衡临床试验中的集体伦理(探索)和个人伦理(利用),以及投资组合优化中的高即时回报(利用)和低回报可变性(探索)。类似地,我们在统计推断中看到偏差与方差的权衡,在统计建模中看到拟合与复杂性的权衡。
英文摘要
Current challenges to statistics, which offer opportunities for advancing statistical theory and methods, are characterized by complex ethical, theoretical and methodological issues. In many practical applications involving uncertainty, an optimal balance between statistical learning and immediate expected payoff is desirable for the best overall performance of a sequence of decisions. Examples include balancing the collective ethics (exploration) and individual ethics (exploitation) in clinical trials, and high immediate returns (exploitation) and low variability of returns (exploration) in portfolio optimization. Similarly we see the bias-versus-variance tradeoff in statistical inference and fit-versus-complexity tradeoff in statistical modeling.
