目前对统计学的挑战为发展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,为了获得一系列决策的最佳整体性能,需要在统计学习和即时预期收益之间取得最优平衡。例如,在临床试验中平衡集体伦理(探索)和个人伦理(利用),以及在投资组合优化中平衡高即时回报(探索)和低回报变异性(探索)。类似地,我们在统计推断中看到了偏差与方差之间的权衡,在统计建模中看到了适配与复杂性之间的权衡。
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.
