*---------------------Data on Physical Fitness-------------------------*
| These measurements were made on men involved in a physical fitness   |
| course at N.C. State University. Certain values have been set to     |
| missing and the resulting data set has an arbitrary missing pattern. |
| Only selected variables of                                           |
| Oxygen (intake rate, ml per kg body weight per minute),              |
| Runtime (time to run 1.5 miles in minutes),                          |
| RunPulse (heart rate while running) are used.                        |
