Variance Components & Spec Setting

Hello all, I am trying to set a bias specification for samples run on an ELISA test involving calibrations. I know I get calibration to calibration and run to run (within calibration) variation in the observed bias when I run, say, 20 samples. I want to explore both cal to cal and run to run variation and use the info to set an appropriate spec. I am having trouble finding a resource to read up ...

How does JMP Pro compute the RSquare for neural networks and bootstrap forests?

Dear all, I am wondering how does JMP compute the RSquare for neural nets and bootstrap forest? What are the formulas? For example, I know the calculation of RSquare for least square regression: "RSquare: Estimates the proportion of variation in the response that can be attributed to the model rather than to random error. Using quantities from the corresponding Analysis of Variance table, RSquare ...

To label outliers and export to Excel spreadsheet

Good day, can you help with a question in exporting/labeling ourliers? As the screenshot, the Outliers were identified by using Analyze > Screening > Explore Outliers. They are excluded in the table. How can I export the data into an Excel spreadsheet with these Outliers identified, (for example in a new column) Thank you.

Difference Between Stepwise | All Possible Models and Generalized Regression | Best Subset

Hello, I just wanted to know what the difference was between using Stepwise - All Possible Models estimation and the Generalized Regression - Best Subset estimation method. It seems to me that they should produce equal results if there response is normally distributed. I have JMP 14 32-bit and found that I can run larger max effects using Best Subset, than I can with All Possible Models due to m...

Control charts Alarm Script: identify rows into data table

I would identify the rows associated with the triggered alarms. The handler that is called when alarms are triggered receive the information about the points, in particular qc_sample (and qc_firstRow qc_lastRow). This should be perfect if there is just one chart. The sample identify the row of the table if we have individual measurements. Unfortunately, I have a BY column that splits into many cha...

Plot conventional and reverse CDF on same plot by grouping variable

Hello,Have a question on CDF plots on the distribution platformI would like to plot the CDF of two variables say Y1 and Y2 which are on the same numerical scale but differ by the range/. For example Y1 from 0-100 and Y2 from 0 to 1000. I want to plot Y1like a regular CDF plot with the CumProb going from 0 to 1 and X1 values increasing from 0 to 100.For Y2, I want the X2 to be in decreasing order f...

Selecting Number of Clusters in Hierarchical Clustering

One way to select possible number of clusters in hierarchical methods is to identify the relatively large changes in distance as number of clusters change (see table below). When I look at the actual distance measure from the table (clustering history below dendogram), there is a bigger jump from 3 clusters to 4 than from 4 to 5 (smaller), suggesting 4 may be the right decision. However, when you ...

Beta Generalized Regression and adjusted chi-square values

I have a data set from a two-choice rodent feeding trial. We were testing the effectiveness of 10 deterrents by coating them on seeds and offering them to rodents alongside control seeds that were uncoated. The explanatory variable is which of the 10 deterrents the treatment seed was coated with, and the response variable is the proportion of control seed and treatment seed consumed. The question...

DF Dens for repeated measures ANOVAs

Dear JMP Community, When I run repeated measures ANOVAs with JMP (RMS, with Subject as a random factor), I have noticed that when a certain factor is crossed with Subject, the corresponding DF Den stays independent while the DF Dens for the other factors are put together as “Residual”. Please see Images 1-3 of the attached file on how “DF Den” under “Test Denominator Synthesis” change across imag...

Partition and Pruning

I'm working with a dataset of about 27,000 rows and am trying to use 9 factors to predict a response using the partition function and a decision tree. I'm using both k-means and validation. When I tell JMP to Go, it will split 100-200 times, however the Split History shows me very little improvement after about 20 splits. For what I'm trying to do, I want to back up to the 20th split, but I don'...

I want to use LASSO and Group LASSO in JMP

I'm involved in a project where we are applying lasso to build a logistic regression model from a "black box" set of predictors. I need to get JMP Pro before trying out JMP's implementation. I'm doing all the analysis in R at present. Does JMP Pro also include group lasso? I've found through using JMP Cluster Variables (CLUSVAR) that I can naturally group my predictors prior to group lasso. F...
