Discovering Patterns in Missing Values

I am working on analyzing patterns of missing values in various well log data in a particular basin. What are some ideas on the best way to analyze these patterns using JMP. Eventually, I would like to classify these missing values as missing at random (MAR), not missing at random (NMAR), and missing completely at random (MCAR) and define which geological conditions and drilling operations contrib...

Are nested variables always random effects?

Background: I am currently analyzing data from an experiment where I fed ant colonies either treated or untreated diet continuously for a month and then measured the weight of individual offspring from each colony at the conclusion of the experiment. Because each colony was only fed one of the diets continuously it seems to me that each colony is nested under treatment. Question: How I include col...

Can you show multiple pre-set control limits on a single control chart using phase?

We want to show a control chart that has independent control limits for multiple conditions over time. For example, we recalibrated our analytical tool and we negotiated with the customer to shift the mean of the control limits. Then we switched to a different analytical tool while the original tool was down, and the backup had its own set of control limits. We learned that we can use "phase" to s...

Partial Least Squares Generalized Linear Regression

Are there any plans to extend the PLS model to what I see called PLS-GLM. In this model, the response can be categorical. The model is a hybrid of PLS and a regularization method that allows the response to remain truly, say, binary. That is, the response is not recoded as 0/1 and then PLS is applied as if it were numeric. PLS-GLM has maximum likelihood as the objective function instead of max...

Plot columns from multiple tables in Graph Builder

Suppose I have two different data tables (different files) that have all different columns except they both have latitude/longitude data. Is there a good way to plot the data from both of those using Graph Builder? We've tried concatenating the tables, but that seems a little messy, putting the entirety of table 2 below and to the right of table 1 -- we're just wondering if there's a better way?

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...
