• Categorical variables/New values for categorical variable?

  Hi,  I'm super new to predictive modeling, I'm hoping someone can help.  I have a data set that has 7 variables, 4 of which are categorical (2 nominal, 2 ordinal).  I have partitioned my data into training and validation.

• How to control number of CPU workers in JMP Pro?

  I like that JMP parallelizes computations across all of my 8 CPUs, but the use of the one last CPU is of great inconvenience, since my PC is tied up in computations and is not responsive. How can I instruct JMP to use only 7 (or total count minus 1) CPUs on my PC, preferrably in a way that is persistent across all of my projects and documents (i.e. does not need to be configured every time I open ...
