*-----------------------------Fish2 Data-----------------------------*
| The data set contains two species of the fish (Parkki and Perch)   |
| and two measurements: Length and Width.                            |
| Some values have been set to missing, and the resulting data set   |
| has a monotone missing pattern in the variables                    |
| Length, Width, and Species.                                        |
