  Hello everyone, I have the problem that I like to  use the control chart builder and the Lot numbers I put in the x-axis do not stay as set, when I save it as script to use again, once my data table is refreshed. I got four control charts save in the script and usually the first one has the set right, but the other three don't. So every time I start the script I have to set the last three control ...

  Hi. Being new to JMP, I'm sure this is a typical beginner's mistake. I need to convert a decimal number to a whole number without rounding. Example 1: The value 0.5986 is copied from column1 and saved to column2. 0 should be saved to column2. Instead 1 is being saved.Example 2: The value 1.5986 is copied from column1 and saved to column2. 1 should be saved to column2. Instead 2 is being saved. I'v...

• 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...
