Compositional data analysis

Hello All,1 - Are there any good examples or any option in JMP Pro to run compositional data analysis before I run PCA and modeling with the compositional data to predict some responses? Let's say I have 20 variables (powder oxides found by X-ray fluorescence, some of which can be zero that need to be imputed, if I use, for example, R, before centered log-ratio transformation), and the summation o...

Retrospective Power Analysis

Hi,I've just performed a t-test that was inconclusive, so I was using the retrospective power option to get a feel for whether it's worth performing additional tests.So, I select Power from the One Way Analysis red triangle and get the retrospective power options.The table has the alpha, sigma and N direct from the existing data. But the table shows a delta of half the difference in means observe...

Interpreting PLS regression coefficients for a binary categorical variable

I used Fit Model with the Partial Least Squares personality to create a model for a continuous dependent variable. Explanatory variables include several continuous variables and a categorical variable with two options, A or B. I understand that option A and B are treated as separate dummy variables. When I run the fitting, the regression coefficient for option A is about -0.4 and the regression co...

How do I calculate z-scores at different aggregation levels?

Hello, How do I use JSL to calculate Z-scores at different levels of aggregation? I am working with cancer mortality data (1999 - 2015) at the county-level. I need to calculate Z-scores to compare each county to the others within a state and all counties within the country. I cannot simply use the standardize function because it automatically takes an average of rates--which is invalid unless the...
