  • Finding first and last elements in a column with a By variable

    Hi! I'm investigating what happened to continous variable (tank level in this case) during certain events. I have an Event.Date column that acts as a By variable. Event duration varies, see DayOfEvent column. I want to calculate: LEVEL @ end of event - LEVEL @ beginning of event, i.e. last element - first element by Event.Date. If positive, tank was filled, if negative tank was emptied, if ~0 tank...

  • Determine significance of difference between percent differences

    I have four sets of data from two experiments: one set of "before" measurements and one set of "after" measurements for each experiment. For each experiment, I have calculated a percent difference between the mean of "before" data and the mean of "after" data. I would like to know if the difference between the percent difference calculated for Experiment 1 and the percent difference calculated for...

A logistic fit X is generated:  It appears to me that with higher age the frequency of subjects recieving milrinone is higher. Quite the opposite is true, if I turn the variab...

  • Log-normal process capability

    Hi, I have a process that is log-normally distributed and has an upper spec limit, and I'd like to calculate a Cpk. I tried two approaches that gave me different answers: Save spec limit as column property for process. Plot distribution of process, then Continuous Fit --> LogNormal to get a Cpk (checking goodness-of-fit of course)Add new column. Set column formula as log(process), save column uppe...

  • Custom DOE - factor levels

    I want to create a custom DOE.  I have 1 discrete numeric vatiable with 3 levels (1,2,3).  I have 2 covariate factors.  I also has 1 continuous variable.  The problem is I want the DOE with 5 levels for the continuous factor and JMP is only allowing me 2 levels.  Am I doing something wrong when I specify the continuous variable or am I limited to just 2 levels?

  • 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).

  • 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.
