The Sashelp.Fish catch data set contains measurements of 159 fish that were caught in Finland’s Lake Laengelmaevesi; it is used to illustrate discriminant analysis. For each of the seven species (bream, roach, whitefish, parkki, perch, pike, and smelt), the weight, length, height, and width of each fish are tallied. Three different length measurements are recorded: from the nose of the fish to the beginning of its tail, from the nose to the notch of its tail, and from the nose to the end of its tail. The height and width are recorded as percentages of the third length variable. The following steps display information about the Sashelp.Fish data set and create Figure B.7:
