Choosing factors in model building with forward stepwise regression

Hello! I am using JMP 13 in my master's thesis in order to build a statistical model. I am new at building models, so I apologize in advance if my questions seem a little basic, but any kind of help would really mean a lot to me. In my master's thesis, I did a Definitive Screening Design (6 factors + 2 fake factors, 7 responses, 17 runs) in order to study some process. After completing all the exp...

Cox proportional hazards

Hi!I am very new to this forum and to JMP&statistics in general. I would appreciate if somebody could advise me on a following issue:I am analyzing whether certain factors (A, B, C etc - all of them are continuous variables) are predictors of a disease (X) incidence. I have 2 independent groups of patients (group 1 - healthy, and group 2 - those ended up with a disease). I need to adjust those fac...

Not all parameters calculated in Choice Model

I have followed the help for running a choice model on the attached Profile and Choice Data. I can't understand why the Tube, Generic, and None parameters don't show in the results (see attached JPG). There are four attributes, Format (4 levels), Shape (2 levels), Colour (3 levels) and Logo (2 levels). There are three profile ID choices, and the test is weighted by 'Test Cell' which seperates 4 di...

Find R_HOME on mac

I'm running JMP 13 on Mac Pro. I've searched the discussions for this, but everything talks about setting environmental variables in windows - I've seen nothing about Mac. I have a couple of versions of R installed. In my Rprofile.site I've defined libpaths and libraries. When I bring things up in RStudion and check everythings works fine, including R_home (this is for R V 3.4.3). From RStudio:> ...

On graph builder, I'm trying to draw graphs showing relationship between particle size and different solvent ratios used.I NEED to display the ratio on the x-axis as 1:4 1:8 1:16 regardless of the particle size, but instead i can find some sorting ways using corresponding particle sizes (ascending or descending) Attached is the preview of the window i'm working on now , and the data sheet itself...

Graphs repeated measures ANOVA

Hi, I am doing a repeated measures analysis and while making the graphs for one of the variables got stuck. So this graph has a group variable on the X axis(nominal) and the Y axis has 4 values of DNA (continuous) at 4 different time points. I got the graph neat and nice but the x axis shows values for both groups separately while I want them side by side. e.g. day 0 DNA both groups together, Day ...

How to predict an output on a table of inputs based on a Gaussian Process model ?

Hi,I am a new user of JMP and I have done a design of experiment (Latin Hypercube) that gives me the values of an output (Y) depending on 3 inputs (X1, X2, X3).I have then analyzed this (X, X2, X3, Y) table with a Gaussian process model. I now would like to use this model to predict Y on a dedicated table of (X1, X2, X3) values.Is this possible ?In the model I can predict Y at one (X1, X2,X3) usin...

.jsl scripts will lock files even while set to read and execute permissions only

I am having an issue where an add-in script which runs another script via the include(); function is locking the included script file while other users are running it. This renders me unable to update that script. I tried setting the permissions on the repository and the file as read and execute only but it still locks when other users access it.

Sub-sampling data analysis in JMP

In Biology (Plant Sci. and Agriculture) usually we have sub-sampling data for replicates. It's very difficult to analyze these data in commonly use Stat S/W (SPSS/Minitab) because MSS(Error) is calculating wrongly. Without taking averages of samsamples, the easiest S/W for this is using JMP and I need some assistance for this. I've found very useful Youtube video about subsampling in JMP (CRD: S...

Conceptual question about the profit matrix

This issue has been discussed previously, but I keep finding myself confused about how to use the profit matrix. My question is conceptual in nature, so let's just use some simple numbers. Suppose I have data on customer churn and I build a predictive model for churn (the particular technique does not matter for this question). My decision errors are not symmetric, however, so I want to modify ...

Cox Proportional Hazard - adjusting risk ratio with std dev

I'm working with someone who is using SAS and I'm trying to do the same analysis in JMP. When I questioned their hazard ratio they said it was adjusted by the standard deviation. They commented:In order to obtain results in units of 1 standard deviation – you simply get the standard deviation value for parameter of interest and introduce it in the PH regression statement, for example:proc phreg ...
