  • Joining Two Sets of Data, between Dates, by Identifier.

    Hi all, first timer, I am trying to combine and match two different tables/data sets from two different sources, with very few unique identifiers... Process example: A widget is processed (in this case with two different reagents), and the output table (below, one row per event) contains "Operation Start Date Time" and "Operation Completion Date Time". The unique identifier for the widget is "SFC"...

  • How to append data to a file without opening it?

    I need to append new data to a file on a weekly basis.  Is there a way for me to do so without opening/loading the file in JMP script? dt = open("my.csv"); dt<< Concatenate(Data Table ("New data") , append to first table); dt << Save("my.csv", Replace(1));  Thanks!

  • k-NN visualization in JMP

    Hi folks, Longtime JMP Pro user here but fairly new to working with the k-Nearest Neighbors classification module.  I'm working with a visible reflectance spectroscopy data set for a geological material classification (two-class) problem.  I have a fairly well-optimized k-NN model at this point with a low misclassification rate on my test set.  So far, so good.  However, I am looking for a way to ...

  • JSL - Find % of missing data

    I have a data table with 3 columnsI need to create a table showing % of missing data in the HEIGHT column grouped by ID and SUB_ID. In the case above the result should be: But it is possible in some cases that there are no rows with missing data. In that case Percent Missing should be 0. I need help in writing a JSL script for this. I will appreciate any guidance. I have three issues in my script ...

  • Looking for a sample size calculator for defect proportions that can help me optimize the sample size with a minimum proportion to detect and the CIs for computed proportions.

    Use case: 35,000 defects detected by a machine on one wafer. An operator samples 1500 images and sorts them into 10 categories. The percentages of the defect categories are meant to reflect the defects in the population of 35,000. In this case 1500 images were used but what happens when the 5000 images are used? What does that do to the confidence intervals on the proportions. As the sampling gets...

  • How is JMP STD error for means and STD error for Mean difference calculated? I wish validate the numbers I get in Excel with JMP

    How does JMP calculate the Std Error of means and Std Error of Diff in the LS means Table and LS Means Differences Student's t. I tried to replicate the results by STD error calculated from both Standard deviation of sample and population,but the values do not match. Please refer the document attached, I calculated the  STD errors from the values in 4 groups as well as theSTD error of the 4 means ...

  • 4PL fit failure

    I am trying to get to the bottom of an odd observation when trying to fit data using a 4PL. In short, when I fit my data I end up with a flat line:  If I do any of the following I end up with a more proper looking fit, and I am sure that other minor changes to the numbers themselves may also fix this bug:Change 0.08 to 0.0800000001Change 26042 to 26043Invert the way the data is within the table (w...
