Hello
When I loaded StatisticsNonlinearFit, I got the msg that NonlinearFit
was used by many packages so some commands or such might be shadowed by
more global terms. Then when I tried to reproduce the example in the Mma
book on-line (3.0), nothing evaluates, even when I tried it inside the
example.
The example has:
<< Statistics`NonlinearFit`
data = {{x1,x2,y},...}
NonlinearFit[data, theta1 theta3 x1 / (1 + theta1 x1 + theta2 x2),
{x1,x2}, {theta1, theta2, theta3}]
The helpfile prints an expression in x1 and x2..what you would expect to
happen, but if you actually activate the cells, you get the NonlinearFite
fcn printed again, with nothing evaluated.
Is it caused by the first msg I got?
How can I get NonlinearFit to work?
Thank you,
Laura
