Hi, everyone,
My question is: It's not every time that you can get a converged
result from the nls function. Is there any solution for me to get a
reasonable result? For example:
x - c(-0.06,-0.04,-0.025,-0.015,-0.005,0.005,0.015,0.025,0.04,0.06)
y -
Below is one possibility:
If you knew MA you would get a regular linear
least-squares for parameters A,B and constant which
can be easily solved. So now you can define a function
f(MA) which returns that value. Now you must minimize
that f - a function of one argument. It can have
several local
