Hi!
I am quite new to JMP and I would really appreciate your input regarding the following analysis.
I have to establish the precision of an assay.
I performed a test that consisted in measuring my sample in x replicates, twice a day for 20 days, on 3 instruments located in 2 different sites (1 in site A, 2 in site B; site A had different environmental conditions and operators performing the test compared to site B).
I assume that these 4 factors are nested as follows:
- Site
- Instrument (nested in Site)
- Day (nested in Instrument and Site)
- Run (nested in Day, Instrument and Site).
I would like to have the following outputs (expressed as CV%):
- Precision within the same run
- Precision between runs
- Precision between days
- Precision within the same instrument
- Precision between instruments
- Precision between sites
- Total precision.
Can this be done in JMP? What approach would you recommend me to use?
I am also supposed to analyze the data via ANOVA. Would I have to perform a four-way nested ANOVA? How can I do this in JMP?
Thank you very much in advance.
C.
