The Fish data set contains measurements of 159 fish caught in Finland’s Lake Laengelmavesi (Puranen; 1917).

The following list describes each variable:

species

species of fish

weight

weight of the fish, in grams

length1

length of the fish from the nose to the beginning of the tail, in centimeters

length2

length of the fish from the nose to the notch of the tail, in centimeters

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
