I was thinking. If you calculate the model with a implicit error function. Then its possible to get complex numbers. However complex numbers provide additional ’svängrum’ (rotational room) for the model.

So I made the implicit error function give two solutions where it could give a complex number. It turned out. The solution gave a double root. That is. Two equal complex numbers. Then all I had to do was to take the absolute length of the number.
