how do you get an r2 and AICc value for a custom nonlinear regression model? How do you adjust the curve for built in regression models?

I don't know what equation best fits the line. I think that the curve for some of my data looks like a power function. Since I don't know the exponent, I used the custom model for nonlinear regression. I need an R2 and AICc values to compare different models. I created a column using the power equation and then went to analyze to modeling to nonlinear and put in my y values and then put in the pow...

What is the meaning of numerical arguments in Legend or Overlay functions?

Hi,I am a newbie to JSL. I am very confusing about the argument values of legend and overlay functions in Graph Builder. For example, 19-21 and 25-27 in the following script. When I change these values, the graph seems no changes. Besides, I found "Overlay( 0 )" in some scripts. What are the meaning of these values? Thanks a lot in advance! dt = Open("$SAMPLE_DATA/Hybrid Fuel Economy.jmp"); dt <...

Update X-Axis while grouping in Graph Builder

Hi Everyone,I have a query. If I have a table like below. If I plot TIME on X-axis and group the X-axis by TYPE. It will shows all five values on X-Axis for both groups, even if their is no data for that. It unnecessarily using the graph space. One way is I can nest the X-axis(TIME) with column TYPE but this works only when both columns are of type nominal. Is their a way if both columns are of di...

How to interpret Predictor Screening results and is this general

Hi there!I'm a masterstudent in bio-engineering and I'm currently working on my thesis, which includes a lot of data processing. I have 66 features of a signal in about 248 windows (each 5 seconds), which are the input of my classifier. The ouput is the level of a specific symptom, an ordinal variable. I wanted to apply 'feature selection' before the classification because I want to know what phys...

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...
