  • How to draw Control Charts that ignore missing data?

    Hi all. Sometimes we take a sample and test it for a number of parameters. On occasion, we don't need to test all parameters, so the data table can take the form of the layout below, whereby A or B can have missing values. When I draw control charts, the control chart leaves a space for the empty cells (per 1st chart below). Obviously, I'd much rather it looked like the 2nd chart below, whereby th...

  • Design an experiment anticipating autocorrelation.

    Is there a way to anticipate and account for potential affects of previous runs in an experiment?     Two use cases: Lab - Samples are prepared using a mixer that cannot be (cost effectively) fully cleaned between runs.  The samples are later treated using a process that, again, cannot be fully cleaned between every run.Continuous Process - A process is not shut down between runs, rather new condi...

  • Basic question regarding CUSUM SPC Charts in JMP

    @martindemelCUSUM charts in JMP are based on the target and the sigma values, which are being calculated by JMP. In my understanding, the target value is the mean and sigma is the standard deviation of the data set.However, JMP generates values which are different to the mean and the standard deviation.I'm wondering what JMP is exactly calculating. The following JSL shows the differences:Names Def...

  • Capability Indices calculation for Nonnormal Distributions in Percentile Methods

    Hi, I would like to figure out how JMP 16 Calculate Ppk in non-parametric method. So I calculate Ppk in R code with the formula in online documentations, but the results are very different. Could anyone help me to understand if it is my calculation error or the documentation?

  • LDA vs Predictor screening to determine which process parameters describe differences between runs

    Currently I'm investigating a unit in a chemical process. This unit runs for several months before it's cleaned. The performance differs between runs. My performance indicator for a run has 3 levels: Low, Med, High. There are about 30 process parameters (pressures, temperatures etc) identified as candidates that could describe/influence the performance indicator. These process parameters vary duri...

  • How to remove empty rows when importing excel in JMP

    Hi All,

    I am importing an excel file to JMP. There are many empty rows in excel (I can not delete them manually as there are 10s of such excel files) and when I import them to JMP, I do not find any option to delete/remove/suppress these empty files. JMP do show option to suppress empty columns but nothing for empty rows (at least I couldn't find it).  I tried to put "Suppress Empty Rows( 1 )" in t...

  • JMP > GraphBuilder > Parallel Plots >River / Sankey Plots > Maximum Items?

    Hi JMP Community,   I just came across an odd behavior in GraphBuilder with the Parallel Plot > Sankey Plot. If I limit the input to a maximum of 66 rows, the plot looks good. However, if I bump the number of rows to 67 or more,the output is no longer useful: no annotations: Is there a trick to maintain the axis annotations as shown in the first plot? Thanks. Best, TS

  • How to set "characters" as "missing values"?

    My table on JMP has a column that contains both numbers and characters. The table lists down products, and this column records the minimum requirement for a specific performance test. Therefore, the cells of the columns could store one of the three:- a numerical value;- "N/A" when the test is not required to be performed on a specific product (entry);- two alternative numerical value (e.g. 4.5 if....

  • Permutation Tests and Monte Carlo Cross Validations Using the Simulation Platform

    I'm trying to do permutation tests and Monte Carlo Cross Validations with the Iris sample dataset as a MWE for our dataset. I'm not sure if I'm doing things and interpreting output correctly.   1) Create New Formula Column (Random->Sample Without Replacement) for the Species Column for Permutation Test. 2) Create a Validation Column (0.75/0.25 split) and a new Formula Column (Random->Sample Withou...

  • Variability Chart Platform Factor Re-Insert Positions (Not Swapping)

    Hello JMP Community, I understand dragging between any two factors swaps the location pairs in the Variability Chart platform. Is there a way to drag to specifically re-insert the factors instead? For example, can I drag "Layout" between "Horizontal" and "Wafer ID" in the attached screenshot instead of performing multiple drags to have the intended result? I am aware I can do this reordering with ...

  • Get (x & y) intercept values from linear fit of the linear region of a curve/data and store them in a new column

    I have JMP data table with data from several parts for which a Capacitance 'C' has been measured as a function of reverse voltage 'V' (0 to -5 V in -0.1V step). A plot of [1/C]^2 vs V has a linear part for small reverse bias (say from 0 V to -0.5V and data is available at 0, -0.1, -0.2, -03, -0.4 -0.5 V within this range). How to do a linear fit to the points between 0 to -5V for each part, extrac...

  • Debugger report for finding bottlenecks

    I'm trying to find bottlenecks in a large script with many includes.  I can run the debugger to profile the script but I'm wondering if there's a better way than just looking through each included script for the highest number.  I'm imagining a pareto.     Anyone know a good method to analyze script performance?
