  • Sample size, power and TOST for a comparability/equivalence test against a gold standard

    I have a historical dataset as a baseline (key product measure) for a manufacturing process, then the process has changed due to optimization. How do I: 1)  estimate sample size and power for a comparability study? 2) use TOST to establish if the product from the optimized process produced the same/comparable product? (assuming equal variance between the 2 datasets) For the 1) my current approach ...

  • reporting R-square for customised nonlinear model fit

    I am trying to find the best way to report a nonlinear model fit to my experimental data.    I have managed to write a script that fits a nonlinear model and finds the parameters estimates using the loss function. It then reports each parameter estimates and the non linear errors. However, I would like to get the RMSE or R-square of the resulting fit also. Is this not available for nonlinear model...

  • Cross Correlation Prediction

    Hi,I have data and cross correlation in between group (L1& L3), (L1 & L4), (L2 &L3),and (L2 &L4).Can one predict what the correlation between group (L1 & L2) or (L3& L4) is from above correlations?  Thanks for your help.

  • Dynamic Time Warping DTW

    I'm a bit confused about how to use DTW. My data ~300K rows with:1st column - test number 1 to 42nd column - time. For each test, time starts at 0 and goes up in increments of 0.2 ms.Eight columns of measurements.Rows are ordered by test and time. What is the proper way to align with DTW? Thanks

  • probit analysis - fit testing (regression) and replicates

    I'm trying to determine the ec50 (concentration at which there is 50% radial fungal growth compared to the control) of certain fungicides I've tried in vitro (in petri dishes) vs different isolates. I have tested the same 9 different isolates with different fungicides as radial mycelium growth. For every fungicide there are 5, 6 or 7 (depending on the fungicide) concentrations tested and 3 replica...

  • Mean separation letter from test slices

    Hello!

    How do I get the mean separation letter in for each level of a factor when interaction is significant? For example, if I have A*B interaction and I want to get the mean separation of B at each level of A, how do I get the LSD letters in JMP? I can do test slices and that will use the DF of the full analysis, but this does not shows which mean of B differs. If I do multiple comparison: How ca...

  • 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...
