stackloss


  The data consist of 21 observations on stack-loss
 (the loss of acid through the stack) in a chemical plant for
the conversion of ammonia to nitric acid, with three explanatory
variables: air flow(<code>x1</code>), cooling water inlet
temperature(<code>x2</code>)  and acid concentration(<code>x3</code>).
