林业野外调查数据中经常混有异常数据,所以在林业回归分析中应用稳健回归的方法将是很有效而且很必要的。文章对稳健回归的主要方法进行了简单介绍,然后针对稳健回归计算复杂、计算量大的问题,提出了直观、简单,易于被林业工作者接受的计算机图解法,用图解法确定稳健一元回归的初值和诊断异常点,方法简单,结果满意。 It is often very effective and necessary to apply robust regression methods in forestry regression analysis because of abnormal data often mixed in forestry field survey data. In this paper, we briefly introduce the main methods of robust regression, and then we propose a computer graphic method that is intuitive, simple and easy to be accepted by forestry workers, and uses the graphic method to determine the stable one-dimensional regression Initial value and diagnosis of abnormal points, the method is simple, the results are satisfactory.
