Prediction Profiler with Mixtures

I found out something intringuing, which can be easily seen by using the jmp file called "Donev mixture data.jmp".Any Mixture DOE table can be used as well.The thing is that Prediction Profiler curves are different depending on whether your ingredient factors are defined as "Mixture" in column settings dialog box, or not.Image 1 shows the column settings dialog box, in where you can indicate wheth...

entering the last value of a list

I'm attempting to get the last value from a list that was created using the following:x = :Values << get values; I tried using x[n rows()] since I know that works with the get as matrix() function, but the list is nominal and I keep getting an error. Any help is appreciated. I'm using JMP 11

Is JMP predicting 0 or 1 in Logistic Regression?

In logistic regression, the outcome has to be coded as 0 or 1. In every program I've run in SPSS, SAS, etc., logistic regression models predict the outcome (y) coded 1, relative to 0. Am I reading my output correctly that JMP is predicting the 0 outcome instead? "For Outcome1 odds of 0 versus 1". Shouldn't this be "1 versus 0"? If it is 0 vs 1, how can I reverse that? I see there is an "Inverse P...

Moving Average with Missing Data

I'm trying to calculate a moving average of some data that has some holes in it. I can't seem to figure out how to caculate a moving average that only includes non missing data and that only calculates the result for rows with non missing data. Any suggestions would be appreciated. New Table( "Untitled 5", Add Rows( 30 ), Compress File When Saved( 1 ), New Table Variable( "Moving Avg Window...

Script formatting for Variability Charts

Hello, I am trying to script a series of Variability Charts in a single Window, which I could save to a JRN or pptx later. Each chart is intended to display the values (in Y) of different parameters (e.g. Height, Weight, Length) with different combination of independent X axis {due to this reason, I could not script it as By( :Parameter_Class ) } in a single Variability Chart platform. Probl...

Can someone help me with PC settings to improve analysis speed?

Dear friends,I have Intel Xeon Processor E5-1650 v3 (15M Cache, 3.50 GHz, 6cores) with windows 7.My system stop responding sometimes. For instance, I have just 12000 data points each with 95 columns. When I do a fit model with full factorial using just 20input variables, system stops responding. Also when I use multivariate analysis, parallel plots etc with the same data it is extremely slow. But ...

Why there is a constant component in the PCA formula

Removing values from a column

Hi All, I would like to remove values from a column. Normally, I would use a range check column property to do this, but with this particular column, it is also dependendent on another column's value. Is there an easy way to do this? I tried the code below, but unfortunately it makes the entire column blank except for the first row. I thought this might work because the "." represents missing v...

Odds ratios for multiway tables

On twitter earlier today, someone asked if the Cochran-Mantel-Haenszel (CMH) odds ratio (OR) test was available in JMP when the stratification variable is not the X in Fit Y by X. Anytime I need to go from two variables to more than two variables, the first place I look is Fit Model. The beauty of fit model is that not only can I use as many variables as I want, but I can consider interactions bet...

How to find ETA squared effect size for MANOVA?

Hello, Does anyone know how to calculate the eta squared value from a manova analysis in JMP? I know that the E and H matrices tab shows the sum of squares for each parameter, but which values do I use to calculate SStotal and SSeffect? In my model, I have 2 control variables (age and gender) and then a two way factorial. If only one of these variables (in addition to both control variables) is si...

Is there an easy way to get the FWHM (full width half max) of a curve using JMP?

Dear JMP community,Is there an easy way to get the FWHM (full width half max) of a spectral curve using JMP? Finding the minima and maxima are fairly straightforward, but then calculating the FWHM seems to be much more laborious in JMP, especially if the data is sparse and we would like to interpolate to get more accurate intersections between the peak and the FWHM value. In my case, the peak is o...

Co-Kriging with JMP and Matlab

Hi!I was wondering if anyone already tried to work with Co-Kriging, using JMP together with Matlab. As JMP only fits Ordinary Kriging Models (Gaussian Process with Gaussian Correlation Function), I would like to send data (generated with Space Filling JMP Platform) from JMP to Matlab, fit the models there (Matlab), and bring the MODELS back to JMP, to use inside Profile Platform. Do you have any e...

Interpreting canonical structure and scores in discriminant analysis

I'm trying to interpret the relative contributions of my variables in a discriminant function analysis of chemical data for three groups of rocks. In a stepwise, linear, common covariance discriminant function analysis I'm able to generate non-overlapping 95% confidence ellipses for my three groups with no incorrectly assigned data points using 6 variables. My understanding is that the scoring c...
