#  Discussion:
#
#    Age and weight are to be related to blood fat content.
#
#    There are 25 rows of data.  The data columns include:
#
#      I,  the index;
#      A0, 1;
#      A1, the weight;
#      A2, the age;
#      B,  the blood fat content.
#
#    We seek a model of the form:
#
#      B = A0 * X0 + A1 * X1 + A2 * X2.
