Table A.3  Blood sugar concentrations (y0 -- y5, in mg/100 ml)
of 36 rabbits at 0, 1, 2, 3, 4, and 5 hours after administration
of insulin dose, with two types of insulin preparation (standard,
x1 = -1, and test, x1 = +1) and two dose levels (0.75 units,
x2 = -1, and 1.50 units, x2 = +1), from a study by Volund (1980).
