EMP GRR : AIAG reproducability

[#1]

using ANOVA from Fit Model and then GRR EMP + AIAG GRR , we are matching the Within Repeatability Variance and Part to Part Variance but :

the Reproducability Variance is expected to be zero ( actually it was negative ) 

Can we get help to understand from where the Reproducability Var component is worked out ?

Please use the truncated data in the files

What truncated data in what files?

[#4]

Here's a document resuming the missing files (I am just uploading it on behalf of the user). Thank you all in advance for your support.

Please upload the JMP file.  The pdf file isn't helpful. How many operators were in the study?

[#6]

I am trying again to upload the jmp dataset on behalf of the user (please run the script "EMP Measurement Systems Analysis of truncated readings by Operator" to see the report the user is talking about)

issue solved : check above , thank you 

[#8]

Based on this Quality and Process Methods > Measurement Systems Analysis > Launch the Measurement Systems Analysis... I would assume it is using REML for variance part of the analysis. How did you model it in Fit Model?

Not sure if I did model this correctly

thanks , issue solved see above 

[#10]

ok issue solved :

Although Var Operators is negative , it is added to Var opx parts to be then var comp , the numbers do match and many thanks to all contributors
