The Answer
Exploit computing technology through JMP™• Interactive by design
− Highly responsive interface with progressive layers that reward discovery.
• No programming required
− Manipulate data, analyses, and plots through GUI.
• Emphasize understanding
− Present statistics and data together graphically.

Going Beyond
JMP Scripting Language enables creation of new applications.• Data table and platforms
• Windows and dialogs
• Matrix language
• Graphics language
• Scene3D (OpenGL)
• Distribution functions
• Random number generators

Random Numbers
Random samples of data are based on chance effects in random processes.
Random numbers are useful in simulations in place of real data.
JMP provides a library of random number generators for many distributions.
