How to Maintain Proportion Balance when Using Subset with Stratify?

Dear JMP Community, I have used successfully the Stratify option when creating subset tables when the stratifying variable has balanced proportions (e.g. 50% Male and 50% Female). Now, I need to create a table subset where the stratifying variable is "unbalanced" (e.g. 25% Male and 75% Female). When I execute the Subset with stratification on Gender, the subset table returns 50% Male and 50% Femal...

Tukey Kramer - Tukey HSD test Unequal Group Sizes

I have read in a reference book for R that the title 'Tukey Kramer' refers to the Tukey tests where there are unequal group sizes. The inference being that Tukey HSD requires groups to be of equal size. JMP refers to 'Tukey HSD (also called Tukey Kramer)' in the sectionBasic Analysis > Oneway Analysis > Compare Means > All Pairs, Tukey HSD . Does JMP demand equal group sizes in each case?

PCA and T-Square T^2

Multivariate Control Chart (from the control chart menu) shows results for Principal Components on Covariances. Doing Principal Components (from the multivariate methodes menu), also on Correlations gives the same eigenvalues and cumulative percentage. Both are scaled. However, the eigenvectors and pc formulas (those that are save to the data table) are not the same. Am I missing something? Thanks

Determine the correct sampling rate for SPC data

Hello, I have an SPC data with UCL = 12.015 and LCL = 12 (target is 120.007) - see attached.My OOC (Out Of Control) values are too high and I want to check that my sampling rate is correct.Current sample rate is 0.1 (1 out of 10 parts are measured) and we are missing OOC measurements (there are 2 groups of SPC values with same limits: "Measure Depth 7" and "Measure Depth 1"). I tried using the sam...

Exact match and Nearest Match for updating a table with another table

I have a big data table (1M rows). One column is serialNumber, one column is dateTime, one column is elapsedTime. Another much smaller table also has these columns, but the dateTime is earlier by an small amount (5-20 minutes) and the elapsedTime is a much more accurate value. The small table also has lots of extra rows associated with other events at other dateTimes (I do not have an 'event' c...

repeated-measures ANCOVA: How to perform the analysis when the parallel slope assumpt. doesn't meet?

Hi all,I need to perform the ANCOVA for a repeated-measures design. I tried to adapt the Julian's ANCOVA procedure showed on the https://www.youtube.com/watch?v=mApbp1RDy-U to my study case (repeated-measures design). Initially, I did the following actions: 1. In the Fit Y by X dialogue: I selected VAR_Y as "Y, Response" and VAR_X as "X, Factor";2. For "Group by" I selected the variable Timepoint;...

Time Series - Prewhiten

Hello Everyone, My question pertains to understanding what the terminology in JMP's prewhiten platform means.Also, understanding how that helps me determine an appropriate Transfer Function that I can use to test whether x causes y. JMP's prewhiten output shows three different ACF's labeled "Prewhiten Corr", "Noise AutoCorr", & "Noise Partial AutoCorr".
What is the Prewhiten Corr, Noise AutoCorr, &...

Fit Spline By Group: Save Spline Coefficients to Column?

Hi all--having an issue. I am using Fit Y by X to fit 5,000 separate regressions. I hold control, select red drop-down arrow, and Fit->Flexible, Fit->Spline and select, say, 0.1. This fits a spline to all 5,000 graphs with lambda of 0.1. I have 28 X values in each of 5,000 graphs, and I understand there are 4 different spline coefficients (A, B, C, D). I understand if I just had 1 regression...

Why does Profiler not stop

All,
I have a script I am trying to profile and improve on. When I run the script without the profiler, it runs and ends within 4 minutes. When I try to profile the script, even after a good 5-6 minutes, it does not stop. Wondering why this is happening and if there is a way to use profiler and not run into this. I am using JMP 13.
