| 摘 要： | 吴占鹏．秩协方差分析及应用．数理统计与管理，１９９８，１７（３），７～１０．在随机区组试验中，区组内往往存在土壤梯度差异，使试验误差增大。为此，本文提出秩协方差分析方法，即把土壤差异εｉｊ分解成Δ·ｘｉｊ和δｉｊ两个成份，从中剔除土壤梯度差异Δ·ｘｉｊ对试验精度的影响，以提高试验结果的可靠性

| Abstract: | he difference of soil step in the blocks make experimental error increasing usually in randomized block design. So we give the analysis of rank covariance in this paper to increase reliability of the results. This method decomposes the difference of soil εij into Δ·xij and δij to get rid of the effect of Δ·xij on the experimental precision. |
