- length3
- length of the fish from the nose to the end of the tail, in centimeters
- height
- maximum height of the fish, in centimeters
- width
- maximum width of the fish, in centimeters
In addition to these variables, the data set contains the following transformed variables.
- cubeRootWeight
- cube root of the weight
- scaledLength1
- the ratio length1 / cubeRootWeight
- scaledLength2
- the ratio length2 / cubeRootWeight
- scaledLength3
- the ratio length3 / cubeRootWeight
- scaledHeight
- the ratio height / cubeRootWeight
- scaledWidth
- the ratio width / cubeRootWeight
- logLengthRatio
- logarithm of the ratio length3 / length1
