Likert scale in correlation analysis

Hi all. I am working on my master thesis and are struggling with my correlation analysis.My plan for the statistics from my survey are:Item analysisPCA and factor analysisCorrelation analysisMultiple regressionCluster analysis. In my assumptions in correlation analysis I have problems with the fitting of the likert scale data to find linearity among other things. Is it better to use the factor sco...

How to calculate moving average of column with 10 million entries ?

I am trying to run the below formula on a column with 10 million rows to calculate the moving average , but the script keeps running forever and jmp stops responding: thisTable << New Column( "av", Numeric, Continuous, Formula( Mean( :x[Index( Row() - 99999, Row() )] ) ) ); Is there any limitation or something wrong with the formula. How can I calculate the moving average in this case?

Statistical significance test for multiple linear regression model

I assume that for multiple linear regression model in JMP, Lack of Fit's p value test (Prob > F) value signifies whether the whole model is significant or not right? Is it the case that if the value is less than 0.05 then we consider the model as statistically significant? What is the use of Analysis of Variance then or is there anything helpful for it's (Prob > F) value for the result findings?...

Weighting Observations

I'm trying to pull some summary statistics out of a weighted dataset (e.g., proportion of the population that has blue as a favorite colour). However, JMP does not seem to automatically weight counts. Is there a way to get JMP to produce the weighted count? Thanks for your help.

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...
