I have some questions about feature selection and inverse prediction. 1) When I use stepwise logistic regression for feature selection, I cannot find the option for "stepwise regression" from Personality drop-down list. Is stepwi...

Ternary plot and background grid issue with JMP 14

Hello,Since I moved to JMP 14 I have this issue when plotting ternary plots with Contour fill: a grid is systematically drawn with thin white horizontal and vertical lines (see captures), whatever the Color theme chosen for the Contour fill. This issue was not present in my previous JMP versions until JMP 13. Any idea to remove these thin white horizontal and vertical lines? I can't manage to remo...

Select Where(Contains()) Usage

I often find that the Contains() function inside the Select Where() function can be convenient. What if I would like to select all rows where a designated column contains the string "a" when it is followed by a number? For example, in a column with the values "a", "a12", and "absent", only the row with "a12" would be selected. Thanks for any tips!

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...

Mean separation letter from test slices

Hello!

How do I get the mean separation letter in for each level of a factor when interaction is significant? For example, if I have A*B interaction and I want to get the mean separation of B at each level of A, how do I get the LSD letters in JMP? I can do test slices and that will use the DF of the full analysis, but this does not shows which mean of B differs. If I do multiple comparison: How ca...
