  • How to fit a normal distribution of specified mean and standard deviation to a data set?

    Suppose I create 100 values from a standard normal.While my parameters are mean=0 and SD=1, the calculated statistics from the 100 data will not be fully equal to the parameter values.If I use "Analyze" and "Distribution" I get a histogram of the 100 random data values and I can fit a normal distribution to these values ("Continuous fit" / "Normal"). The fit is based on the statistics of the data....

  • How do you design an experiment when one factor depends on another?

    I want to use design of experiment principles to select factor levels for an test. For the system of interest, one easy to change factor depends on a more difficult to change factor. How do you define the levels in a statistically valid manner? To illustrate, say I want to study the performance of a machine. One of the factors of interest is operating speed, a factor with 7 levels than are is most...

  • How do I choose between a Wilcoxon, Wilcoxon Signed Rank, or t-test with matched observations?

    I'm new to JMP, and trying to determine which test is appropriate for my study. I have matched biological measurements at two time points (before and after a meal) for 25 individual donors. Each donor has a single data point per time point. The population has a large standard deviation for most of these measurements, and usually the results do not have a normal distribution. Some observations have...

  • how to select rows with a specific number that user input

    Hello everyone, I am working on a project that helps users to pick modules based on their input. For example, if user input 5, the script would give user 5 modules that been selected. Could anyone one help me with the "select" part?

  • 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;...

  • 8-run Plackett-Burman with JMP14

    Hi everyone,How can I perfrom an 8-run Plackett-Burman design with JMP14? Browsing the online documentation about Plackett-Burman suggests to include 4 additional runs and construct a 12-run Plackett-Burman design instead. However, a 12-run is just too much as I only have 4 factors... so a PB-8 would be enough for me. Unfortunately, after choosing Classical > Screening Design and setting the respo...

  • 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.
