Minitab交叉方差分析的方差分量和标准差excel里怎么计算
本帖最后由 a05558 于 2018-10-15 21:42 编辑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:
ComponentFormula
RepeatabilityMS Repeatability
Operator
MS Operator - MS Operator*Part
a*n
where a = number of parts and n = number of replicates
Operator*Part
MS Operator*Part - MS Repeatability
n
where n = number of replicates
Part-To-Part
MS Part - MS Operator*Part
b*n
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:
ComponentFormula
RepeatabilityMS Repeatability
Operator
MS Operator - MS Repeatability
a*n
where a = number of parts and n = number of replicates
Part-To-Part
MS Part - MS Repeatability
b*n
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.

用教材上的 均值-极差法方法 计算EVAV TV GRR,算的结果和minitab上对不上 :) :) :Q:Q 谢谢分享。。。 谢谢分享。。。 这是软件自动计算的。手工计算的话工作量大得很!
