摘要

本文主要研究拉丁方设计中异常值的检测和处理。箱形图方法用于检测离群值，通过将其保留在数据中或考虑其缺失值来研究其影响。从实际工作中得出，离群值对均方误差值有明显而重要的影响，对离群值进行处理后方差分析的结果较好。

Study the effect of outliers in Latin square design

The present focuses on detecting and treating the outlier values in the Latin square design. The box plot method has been used to detect the outlier values, their effects have been studied either by keeping them in the data or by considering them missing values. From the practical work it is concluded that the outlier values have apparent and important effect on value of mean squares error, and the results of analysis of variance have been better after treating the outlier values.
