General Linear Model 问题求教?
求教高手以下问题:使用minitab STAT>ANOVA>General Linear modele 对数据分析结果如下:
General Linear Model: 设计縮水率 versus 原料材質, 产品类型, ...
Factor Type Levels Values
原料材質 fixed 4 LCP, PC, PC+ABS, PPA
产品类型 fixed 3 Cover, Ring, Upper/lower
产品平均肉厚(mm) fixed 16 0.60, 0.70, 0.75, 0.80, 0.83, 0.85, 0.90,
0.92, 0.95, 1.00, 1.06, 1.10, 1.20, 1.30,
1.50, 1.80
分段产品长 fixed 4 10-40, 41-60, 61-90, 91-130
分段产品宽 fixed 4 1-20, 20-40, 40-60, 60-80
分段产品高 fixed 4 1-3, 3-6, 6-9, 9-13
Analysis of Variance for 设计縮水率, using Adjusted SS for Tests
Model
Source DF Reduced DF Seq SS
原料材質 3 3 0.0000385
产品类型 2 2 0.0000359
产品平均肉厚(mm) 15 15 0.0000175
分段产品长 3 3 0.0000068
分段产品宽 3 3 0.0000003
分段产品高 3 2+ 0.0000051
Error 135 136 0.0000587
Total 164 164 0.0001628
+ Rank deficiency due to empty cells, unbalanced nesting, collinearity, or an
undeclared covariate. No storage of results or further analysis will be
done.
S = 0.000657109 R-Sq = 63.93% R-Sq(adj) = 56.51%
问题一:+ Rank deficiency due to empty cells, unbalanced nesting, collinearity, or an
undeclared covariate. No storage of results or further analysis will be
done. 这句话我如何理解它 ?
问题二: 把:分段产品高 这个变量剔除后再做分析就可以Analysis of Variance for 设计縮水率,可以看p值来判断几个因子是否显著,如果不剔除要如何处理数据?
