Statistical Dispersion of XY Coordinates

Hello JMP Community,I am working on a project and would like to analyze strings of data to determine statistical differences in clusters of XY coordinate data. Specifically, I would like to be able to determine if string 1 is less dispersed than string 2. I have made a mock dataset (attached) that illustrates the type of data I am looking to analyze. Additionally, I have attached a file that examp...

How does JMP determine the best model using AICc in stepwise regression?

How does JMP decide which combination of variables are the "best" model using forward AICc in the stepwise regression module? In other words, how does it decide when to stop, and why does it sometimes decide that there is no single "best" model? I've read that there must be a difference in AICc of 2 or greater, otherwise the models are considered equivocal. Is that what JMP is using also?

Currently where I work we have SAS 9.2 Foundation with QC package, and we have 4 templates, or macro programs, that will run with each of our products. Which we have 40+ products. The problem is, we are the only branch in the company using SAS for our reports and it has been desired for use to do them in JMP. A typical SAS marco for what we currently have is%macro Import(Filepath=) the excel fi...

How to get “Quantile Profiler” and “Distribution Profiler” for a Survival Model in Nonlinear fit?

Hi,I am using the Nonlinear fit in JMP to fit a Nonlinear Parametric (log-normal) Survival Model. After fitting the model, I want to plot the "Quantile Profiler" and "Distribution Profiler" with confidence interval as Survial Analysis Platform does. Is there an convenient way to do that?Any suggestion would be appreciated.

Plotting confidence intervals in parametric survival analysis(Weibull)

Hi all,I am doing a parametric survival analyses (Weibull), and I would like to plot a curve similar to the one below. I could plot the mean (blue trace below), as JMP gave me the formula for it, but I am not able to plot the confidence intervals as JMP wont give the formula. However I could see the plot (mean and CIs) in the "profiler" of the platform.The formula to compute row wise mean quantile...

Help to improve display resolution of a surface profiler graph in JMP itself

My main issue is that the display is very low resolution from the get to go. I've tried to look through settings and I can only see preferences for exporting at 300 dpi or higher but I don't see any settings to change my own display of the graph in jmp too a higher resolution. Consequently even if I export as an eps or vector file, I don't have a good quality picture because it looks so poor from ...

test statistics on odds ratios in logistic regression

I've been using logistic regression with multiple categorical predictors. I'm particularly interested in the odds ratios, and I understand how the odds ratios themselves are calculated, but I'm having trouble understanding how the test statistics associated with each odds ratio are calculated. JMP gives the disclaimer "Tests and confidence intervals on odds ratios are likelihood ratio based." M...

What robust methods are common for Process Capability Indices for Non-Nornal distributions?

In Europe, we found it common to use Cpkn as a non-normal Cpk metric, where mean was replaced with median, and stdev was replaced with IQR/1.35. For some "regulatory" or "customer" reports, this seems to be accepted rather than the usual "torture the data until it says its normal" approach with transformations. Does anyone have similar experience or better ideas? (Note: any use of capabilit...

Graph Builder Remove Variable

Hello,I am trying to use jsl to remove the x-axis variable and replace it with a different one. It looks like I should use the GraphBuilderBox <- Remove Variable() tool, but since I change the x-axis variable multiple times, I do not know its name and would like to use the Remove Variable(Role("X"), Position(1)) method, but this does not work. Any assistance would be appreciated.Thank you,Martin

How to calculate average (median) of a group of variables to get the eudlidean centre

How would I calculate the shape of the average (using the median) of a variable from a group within a data set? I need a certain function for calculating the centre of gravity (centroid) or Euclidian centre of this group of variable.
Many thanks!!
