Here’s a handy little function to apply a transparency effect to a solid (r,g,b) colour:


File Handling

The JMP scripting language has a number of convenient functions for handling files external to JMP.  Here’s an example:


Code Folding

Code folding allows you to collapse a block of code – you can use it  to focus on high-level structure without getting lost in the detail.

To enable code folding enable to option under the Script Editor section of Preferences, found under the File menu.

I use it with my user-defined functions to give me an overview of contents within an include file.  Combined with appropriately placed comments this helps to summarise the contents of a library of functions.  Here is an example:


Reverse Process Capability

Process capability is a well-established technique for evaluating the degree to which a process is capable of delivering a product within specification. But what if the specifications are unknown or at best tentative?

The calculations of process capability analysis can be reversed so that for a given set of target capability values the associated specification limits can be generated. The calculation is straight-forward for a normal distribution but needs a bit more thought when it comes to asymmetric distributions.
