Notes and Considerations
Includes examples of both the Range method and the ANOVA method from the Statistica GR&R Module.
See attached file "GR&R Example 1 AIAG (Statistica).doc" for how-to screenshots.
The GR&R analysis was performed using four methods to emphasize the underlying theory and the equivalence of the methods.
1. The GR&R module Range method
2. The GR&R module ANOVA method
3. The Variance Components module
4. The GLM module
See also the file "AIAG MSA Variables GR&R Example.pdf" that contains an excerpt from the AIAG MSA Manual of the example and output.
Errata (05FEB2011 - thanks to Steve B):
The following Figures/Tables need amending from AIAG MSA v3 to v4 in the GRR Example 1 for AIAG.
Page 8, 9 of 41: Figure 25 from AIAG MSA (3rd Ed) needs to be changed to Figure III-B 16, pg 119 (4th Ed)
Page 18, 19 of 41: Table 9 from AIAG MSA (3rd Ed) needs to be changed to Table III-B 8, page 127 (4th Ed)
