Repeated k-fold Cross-Validation with Stepwise Regression (JSL Script?)

Hi all,Many of us know the variability that k-fold cross validated stepwise regression might have with small samples. It is often suggested to repeat this procedure 50-100 times in order to increase the realibility of the outputs.I was wondering if there is a way in JMP to repeat this procedure? It will save me TONS of time!THANK YOU

Stepwise Logistic Regression

I carried out a stepwise logistic regression in JMP 13.2.1 using P-value Threshold (Prob to enter=0.2, Prob to leave=0.1) and mixed direction. On the same dataset the same analysis in SAS 9.4 yielded a different selection (using Selection=stepwise, slentry=0.2 and slstay=0.1). I expected to get at least the same selection of variables. Did anyone find something similar or does anyone know what the...

Image Classification

I'm interested in using JMP/JSL to do some classification on semiconductor wafer images. Ideally I would like to do this using training images in a machine learning type scenario. Where would one start, is JMP the right tool for this job?

Open Image (jpg) Files, Perform Analysis and move onto next Image

I am very interested in using JMP to do automatic image processing and analysis and I have a script ( heavily based on John Pontes add-in - and information gathered from his excellent blog John Ponte, Author at JMP Blog) that I can run on one image at a time on images but what I really want to do next is to create a 'looping' script that does the following counts the number of .jpg files in a ...

Independent Grouped X Scales in Graph Builder

Hello, I've just seen this Live Webcast "Using Design of Experiments to Increase Predictability, Optimise Processes and Minimise Costs". One of the charts I saw was Graph Builder single chart with several X Scales (X Group) but each X Scale had its own min and max values. Please see attached the image. In that image I would like that each Input will have its own independent X scale. Now, when I sa...

Run .jsl without opening any window

Hi All, Is it possible to run .jsl without opening any windows or data tables in JMP? I am trying to run everything in background if possible. Thanks.

Can JMP 13 do Posthoc mean comparisons for GLMs?

How can I assess whether one mean (from a treatment group) is significantly different from another when running a GLM in JMP 13? I know how to do that in the other model platforms (REML, SLSs), but I can't seem to find that option when performing GLMs. For example, I have a GLM model where the response variable is a logit-transformed proportion value (Y) and all effects are categorical (treatment ...

For one way ANOVA test, why results from "Fit Y by X" and "Fit Model" are different?

Hi, I was trying to do one-way ANOVA test using "Fit Y by X" and "Fit Least Squares", the sample data that I used is "Snapdragon". Originally, I thought the P value and F Ratio I got from both methods should be the same (see highlighted part). However I was wrong. They are actually quite different Could someone tell me why they are different using these two methods? Which one is a more accurate an...

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 ...

JSL How do I wrap the title text of a OutlineBox?

Hi all, I often use the Set Title() message to overwrite the OutlineBox titles of charts, distributions, etc. My first issue is that the OutlineBox does not support the Set Wrap() message. Is there any replacement I could use? To work around the missing Set Wrap(), I started inserting newlines "\!n" in the tiitle text. After doing this, I have noticed a second issue: Whatever number of newlines I ...
