Hello JMP Community,
For context and in case this helps with Google indexing, this is a use case from a proteomic experiment, and the individual "measurements" in the attached example file represents individual peptide measurement.
The Matched Pair analysis already gives me the answer I need (Matched Pairs Analysis (jmp.com))
- Group by "GroupBy"
- Matching two conditions at a time (e.g. Drug00 vs. Drug01, Drug00 vs. Drug02, Drug00 vs. Drug03)
However, since I really just need the two-tailed t test p-value, I currently have to:
- Go through Analyze >> Specialized Modeling >> Matched Pairs
- Select two Y columns at a time (e.g. Drug00 and Drug01)
- by the column GroupBy
- Wait for output with plots and all the t statistics
- Make Combined Data Table
- Sort by Column 4
- Scroll down to "Prob > |t|"
- Select all rows with "Prob > |t|" in Column 4
- Invert select, then delete selected rows
Question 1:
Is there a way to go through JSL or otherwise, to simply tabulate either all the statistical outputs (e.g. Mean Difference, Std Error, Upper/Lower 95%, Prob > |t|), or better yet, just Prob > |t| ? I don't know how to get started, since unlike the Graph Builder, I can't figure out how to "Save Script".
Question 2:
Getting "Question 1" resolved would go a long way for me already, but is there a way to do multiple Matched Pair analysis (i.e. Drug00 vs Drug01, Drug00 vs. Drug02, Drug00 vs. Drug03)?
Analyze >> Screening >> Response Screening seems to be what I'm looking for. Launch the Response Screening Platform (jmp.com)
- Drug01, Drug02, and Drug03 as Y, Response
- Drug00 as X
- Grouping by GroupBy
- Checked: PValues Table on Launch and Paired X and Y
However, it's not clear to me what the PValue column in the output represents.
In addition, the PValue from the Response Screening workflow doesn't correspond to and seem to be smaller than any of the one- or two-tailed p-values I get through the Matched Pair Analysis work flow; the Prob > |t| values from the Matched Pair Analysis workflow seems more reasonable.
Thanks for your advice.
