Scatter Plot Showing Exponential Relationship  
Discussion 
Note that a simple straight line is grossly inadequate in
describing the relationship between X and Y in this
plot of the CHWIRUT2.DAT
data set. A quadratic model would prove lacking, especially for
large values of X. In this example, the large values of
X correspond to nearly constant values of Y, and so a
nonlinear function beyond the quadratic is needed. Among the
many other nonlinear functions available, one of the simpler
ones is the exponential model
