Does anyone know how p value of Actual by Predicted Plot in Fit Model platform?

HiAfter running a linear regression using the Fit Model platform, JMP displays P value (as P), RSq and RMSE on the bottom of the a Actual by Predicted Plot. I would like to understand how P value is calculated and what it means.I ask this because in a simple Y =aX+b case, the p value is identical to the p value of the X but if there are more Xs (e.g. Y = aX1+ bX2 + c) then, p value is something el...

Test of agreement for presence/absence by month

Hi, I collected data on the monthly occurrence of a parasite and the monthly occurrence of a histological lesion in the tissues where the parasite infects. The parasite is strongly seasonal - peak prevalence and intensities occur in March and April. The lesions are more spread out throughout the year but appear to be more common in those months. So for each (lesion or parasite), I can construct...

Converting Between Data Tables and Associative Arrays

Hi there, Is there a simple way to convert a data table to an associative array? I'm trying to pass the associative array to an external API for analysis, and then getting the results back into JMP as a data table afterwards. Thanks! Howard

JSL script for binning

Hi, I have a sparse matrix with 1248 rows and 2435 columns. My first column is CustomerID and remaining are products with quantity ordered by each customer as a value. Each column has a different range. I want to standardize the columns values to 1 - 5 by having cut points at 20 percentile. I found interactive binning addin can help me to accomplish if the number of columns are less. I am new to J...

Col Mean behaviour with hide/exclude

Hello, I observe that when I use ColMean function in one column that the value in the column is not updated when I hide/exclude some rows.I think this is not a normal behaviour - there is no automatic recalculation. May be we can avoid this with script but I would prefer to avoid. If someone has a solution, thank you in advance Regards Sébastien

Multivariate results interpretation

Hi JMP experts! I have a question about how to interpret multivariate results: say I have a data set y, x1, x2 three colums.

My addin can then load the data from the text file. The issue that I have is that the columns vary bas...

.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.
