Simulation of Within and Between Variation for Specification SettingSuppose you characterized the variation in the weight of tablets from a new process and then wanted to use that work to estimate the variation in weight that could be expected in a multi-tablet package.
One way to get the multi-tablet estimate is to simulate a large number of tablets with a specified mean and sigma, using a normal distribution. Then divide the individual tablets into a large number of subgroups, sum the weights and then look at the variation in the subgroup

Re: Simulation of Within and Between Variation for Specification Setting@Byron_JMP .. Thank you!

The most basic simulations begin with a simple formula. For example, Random Normal(10,1). Which returns numbers from a normal distribution with a mean of 10 and a standard deviation of 1.
The next step is to determine how many draws to simulate, and that is just a matter of adding rows to the data table. (from the "rows" tab, pick add rows. ) Some number between 5,000 and 5,000,000 will probably work out well. (its just that 5 million is a little slower.)
JMP has a pretty good library of distribution functions to choose from.
In this article I explain how to use another tool in JMP to do the same thing using the profiler in some ways it is a little more complex, but in others it makes the simulation really easy to set up.

Re: Simulation of Within and Between Variation for Specification SettingHi, kindly explain more on this. How do we do simulation using JMP?
