excel里包含交互作用的双因子方差分析我会算，请教前辈指导后面方差分析量和标准差的算法
终于找到计算方法了
VarComp for ANOVA method Variance component contributed by each source. When Operator*Part interaction is included in the ANOVA model, the variance components are calculated as follows: | | | | | MS Operator - MS Operator*Part | |
where a = number of parts and n = number of replicates | Operator*Part
| MS Operator*Part - MS Repeatability | |
where n = number of replicates
| Part-To-Part
| MS Part - MS Operator*Part | |
where b = number of operators and n = number of replicates
| Reproducibility
| VarComp Operator + VarComp Operator*Part
| Total Gage R&R
| VarComp Repeatability + VarComp Reproducibility
| Total Variation
| VarComp Total Gage R&R + VarComp Part-to-Part
|
When Operator*Part interaction is not included in the ANOVA model, the variance components are calculated as follows: | | | | | MS Operator - MS Repeatability | |
where a = number of parts and n = number of replicates | Part-To-Part
| MS Part - MS Repeatability | |
where b = number of operators and n = number of replicates
| Reproducibility
| VarComp for Operator
| Total Gage R&R
| Sum of the VarComps for Repeatability and Reproducibility
| Total Variation
| Sum of the VarComps for Total Gage R&R and Part-to-Part
|
If a variance component is negative, then Gage R&R will report it as zero.
