Manually Performing a Grubb's Test

Howdy Everyone,I am in the process of creating a JMP appendix for one of our processes and have found it necessary to explain how to manually set up a column formula to perform a Grubb's Test. I have done this in Excel, but i want to replicate that in JMP and have had a hard time setting up the formula correctly. We have 4 columns of independent data (1a,2a,3a,4a) that each need a Grubb's Test ...

Box Plot option in Variability Gauge Chart

When I turn on the Box Plot option in the Variability Gauge Chart, I get a quantile box plot where the whiskers are essentially range bars that extend to max and min values. Is it possible to change the style that is displayed to be the outlier box plot? That would be more useful for my application. Even better (I think), could the extent of the whiskers be customized in some way to extend to s...

Grubbs outlier test and distributions

Hello all. I have a very high value in a univariate dataset and wanted to test if it were an outlier. I have downloaded and used the Grubbs outlier test script. However, the assumption for the Grubbs outlier test is that the data come from a normal distribution -- but I am unclear from the references I have read if this refers to the raw data or the residuals. It has been suggested that what could...

Change all columns names dynamically

I'm opening a text file that I want to concatenate with an existing JMP file. Unfortunately, the column names of the two files don't match and therefore can't be easily concatenated. I'm trying to change the column names of the text file to match those of the specific JMP file it will be concatenated to. To further complicate things, the quantity of columns and their positions change in the var...

Parameter estimates in Logistic Regression

I have simulated three data sets of 20M points each for testing LR with binary response variables with very rare events:1) Two continuous effects: Beta0=12, beta1=1 and Beta2=1. X1 is Normal (-0.8, .25) and X2 is -ABS[Normal (0,5)]. (Each of the two variables increases the probability of the event, depending upon the value of the variable.) In this case there are about 711,000 positive events in 2...

Graph Builder Remove Variable

Hello,I am trying to use jsl to remove the x-axis variable and replace it with a different one. It looks like I should use the GraphBuilderBox <- Remove Variable() tool, but since I change the x-axis variable multiple times, I do not know its name and would like to use the Remove Variable(Role("X"), Position(1)) method, but this does not work. Any assistance would be appreciated.Thank you,Martin

How to calculate average (median) of a group of variables to get the eudlidean centre

How would I calculate the shape of the average (using the median) of a variable from a group within a data set? I need a certain function for calculating the centre of gravity (centroid) or Euclidian centre of this group of variable.
Many thanks!!

Combining multiple screenings in Fit Model?

Hello, I've been using the Screening function to fit my data. It's been working well for individual outputs but I haven't been able to figure out how to make a model with multiple outputs and have it screen for the best fit for each output. The reason I would like to do this is to use the desirability function for multiple outputs, which has been pretty useful in determining the most ideal s...
