If you fit a block as a fixed effect in a saturated model, and its effect is not significant after you reduce it via stepwise regression, do you need to add it back to the model?

This was posted to the JMP blog yesterday where Phil Kay describes reducing a saturated model with a block effect. He says the random block should be added as a fixed effect 1st in this specific case, then after you reduce the model via stepwise regression, you should re-fit the reduced model & add the block as a random effect. In his example the block was significant after he reduced the model. I...

Difference of opinion for Steel-Dwass or Games-Howell post hoc test

For a current study, group sizes for pairwise comparison are problematic, the group sizes are 15, 10, and 5. Because of the unequal group sizes and small sizes (additionally) the researchers are conducting a Welch's ANOVA. Following the Welch's ANOVA the researchers are conducting Games-Howell post hoc either planned or exploratory. The counter argument is being made that if the assumption for hom...

Grouping Data by Rows in JMP Pro 18

I am currently working on a JMP Pro data file (attached), which contains 150 observations covering the years 2015 to 2024. The dataset comprises four columns: “YEAR”, “Location”, “ENT CAP”, and “NEP”. I would like to organize the data by grouping all rows according to the values in the YEAR column. For example, all 16 rows corresponding to 2015 should be grouped under the label “Y2015”, and simila...

Rows inclusion in PCA

Hello, I am running a PCA on an NMR dataset that contains some missing values. This isn't due to an error—it's simply the nature of the data, as some samples do not show certain peaks. I have noticed that when I include these parameters Y variables in the PCA and color the score plot by sample, some samples are missing entirely from the plot. It's not consistent—some samples with missing values...

How can I properly arrange the order of options in the Column Switcher without changing the actual order of fields in a DataTable? In the provided JSL, simply sorting the list of columns does not affect the order of options in the Column Switcher. I have noticed that sometimes the actual order of columns in the DataTable can affect the order of options in the Column Switcher, but other times it ...
