• Control chart Xbar-R for large subgroup size

  JMP is able to produce Xbar-R charts for large subgroup sizes.  What is the equation for upper control limit on range if the subgroup size is 475?  I have 60 subgroups each having a subgroup size of 475.   I already understand how to calculate the control limits on S for Xbar-S, I don't know the equation for UCLR for Xbar-R. Mike

• Parameter tabulation in nonlinear modeling

  Hello JMP community. I am working on a project where I am modeling a nonlinear model to data for multiple part numbers and I want to tabulate the nonlinear parameters for each part number.As an illustration I have added a simple data table for 2 part # with a nonlinear script that models a typical RC circuit decay of voltage for each part based on the equation  V_t = V0 * exp (-t / tau), where V0 ...

• Options for comparing sample size and method from population dataset

  I’m looking for options to compare sampling size and methodology in an RCBD population dataset. The dataset is from an animal floor pen study (14 animals/pen = EU). Weight and other variables were collected from 100% of EU.
  The idea is to look at the dataset and evaluate different scenarios for selecting samples (Randomly from pen, Randomly _# of animals, witching a stand deviation, _# within a sta...

• n rows doesn't mean n

  Hi All, I got some descriptive's from JMP, included in the output was: N Rows, l thought that is handy l would need that later on, unfortunately this is a count of the actually rows and not n, as l have some missing data, is there a simple line of code in JMP that l can get the actual n and not count the missing data, similar to na.rm = TRUE, by groups, the code i used is as follows:dt3 << Summary...

• How can I generate a scatterplot with log-transformed scales on the axes?

  I want to generate a scatterplot for two continuous variables. As each of these variables has a few outlying observations, the scatterplot should have log-transformed axes but with the original variable values as tick marks,
