摘要
讨论了四川桤木林分干材收获模型共线性诊断及其缓解思路 ,认为纠正符号上的错误 ,适当降低偏回归系数的标准差 ,在实践应用上是可取的 ,操作上是简便的。
The paper discussed the determine and solution thought on multi colinear of trunk volume model of Alnus cremastogyne,the authors think that correcting the mark,and reducing the standard difference of incline regression coefficient proporly were adapted in facts and suitable for operation.
