     An experiment was conducted to study the _O2UP_, oxygen uptake in
     milligrams of oxygen per minute, given five chemical measurements:
     biological oxygen demand (BOD), total Kjeldah nitrogen (TKN),
     total solids (TS), total vital solids (TVS), which is a component
     of TS, and chemical oxygen demand (COD), each measured in
     milligrams per liter (Moore, 1975).
