Malfunction in Bootstrap Forest with Tuning Design Table?

Hi all,I have a case where I want to apply a Bootstrap Forest approach in combination with a tuning design table. While following the instructions in JMP-Help I ran into the problem that only two out of the six described hyper parameters in the tuning table made it into the nunmbers of models build according to the run number of the tuning table.Was this issue identified by someone else, too?I alr...

power and sample size calculation in JMP

I'm trying to determine the sample size using one sample mean. The Std. Deviation from the historical study is 5.8E+8 and I don't know how to use it in that platform as the one sample mean has a Std. Deviation limit of 200,000. Any idea how to overcome this issue? Is it possible to use CV in the calculator?

help with model comparsion: DOE vs ANN boosted

Good morning guys! 1) I have a DOE and some boosted neural network models that I would like to compare their respective Rsquared (largest), RASE (smallest) and AAE (smallest) to select the best optimized models from my experiments. I saw that in the "Model Comparison" tool, through the predictive formulas saved in the experiment spreadsheet, I can make the selection according to the criteria above...

Working with Imputed Data in JMP - Elastic Net

Hi Everyone,

I am working with a dataset that went through multiple imputation in stata. I am trying to do elastic net regression on the data set in JMP because Stata does not seem to support elastic net in it's multiple imputation estimate command.

I was wondering, does JMP have any way of identifying the data as MI data, or does it even matter? The mi estimate command in stata conducts a combined...

Undersampling, Oversampling, and weighing

How can I populate my data so I only get undersampling sampling technique without modeling. I need to do the same for oversampling and weighing. I am trying to run xgboost with these three sampling techniques (one at a time of course). So, I need one dataset that shows undersampling, a different dataset for oversampling, and a third dataset for weighing. Thank you.

How do I use the integrate function with a predictive formula generated from a raw data set

Hello!

I'm attempting to find the area under a curve of a data set between specific time intervals (x-axis). I have taken the raw data which was analyte concentration (y) across time (x) and ran it through a fit curve model that generated a predicted equation that fits the raw data with R^2 =0.95.

I'm a bit confused of my next step, I've tried to plug the equation in as a formula in a new column and...

How to optimize factors with uncertainty in 1 step with JMP?

Hello community!!,A question: will it be possible for the profiler to find the best combinations of factors with uncertainty when performing a simulation, which maximize the total utility and minimize the total cost, generating a table of the best combinations found? For example:

Caution: Places where Jmp does something unexpected

Definitely, JMP is Not a Spreadsheet . And that's great!! Besides this difference, there are other places where Jmp doesn't do/behave/produce what a newbie / innocent Jmp user expects.
If a user knows these issues and the remedies and workarounds - he/she can
a) save a lot of time b) be safe from data loss c) be sure that the results are as expected.

Nested Cross-Validation Script?

Hello, how can I apply nested cross-validation outside of the model screening platform? I would strongly suggest to extend the Make-Validation-Column Section by an option to automate nested cross validation for all predictive models. It would be cool to just select a validation column (or 2 validation columns) for nested cross-validation. In the meantime, could you please provide me with an exampl...

SIMCA classification method: what alternative options do I have in JMP and what are the pros/cons?

Hello, I am after a combination of guidance and education. I have recently come across SIMCA as a classification approach. I believe this is not something JMP can address at the moment so my question is, which alternative options can I explore to achieve a similar goal and what would be the advantages/disadvantages when compared to the SIMCA method? I am currently using JMP 17 Thank you very much...
