How to create synthetic data?

Hello!

 

Please, explain how I can create synthetic data using JMP?

Thank you in advance.

Re: How to create synthetic data?

Hello,


First I am assuming that synthetic = simulated data. That is you want to generate "pretend" data based on some underlying assumptions. Another way to generate "pretend" data is by resampling from "real" data. For simulating data from underlying assumptions review the random functions that are in JMP as these will be the tools that you can use for your simulation.

Another place to look for examples on simulations is go to Help>Sample Data and then look on the lower right portion of the window that opens and under the teaching resources is a section with simulations. You can open the simulation tables and look at the column formulas to see how those simulations were set up. This might provide you with some ideas as how to get started on your synthetic data set (add rows to the tables to generate values).  Then, once you get a bit closer, if you still are having trouble, repost with more details and I am sure someone will jump in to help you more.

Re: How to create synthetic data?

I want to generate a simulated database (n=100, for example) following any probability distributions e.g., Logistic, Lognormal, Weibull, etc. I can do it on EXCEL using  Data>Data Analysis>Random Number Generator

However, I do not know how can it be done in JMP Pro 16. 

Can anybody help?

Re: How to create synthetic data?

Create a new column in JMP. Make it based on a formula and look under the Random set of functions. There is a large selection, here is just a subset:
