Hi,
Sorry, DrBob, but you have got my last message in an incomplet form
by some reasons. So I will send my original question again. (see
below) Like Johannes Ludsteck I checked also the NonlinearFit.m package
for the print statment to substitute it but I can't find it (May be it
was moved to the kernel ?) Of cause a "brute force" methode is th set
MaxIterations->1 and start again and again in a loop with the new
output as a new start parameter. For me tihs is not the "smartest" way
to use mathematica because it cost time (CPU and man-power) . May be
the discussion of the topic:
> Re: [mg34786] RE: [mg34749] RE: [mg34709] Re: [mg34705] Is it
possible to access internal variables? can help me, but up to now I
have problems to understand the discused examples.

... may be my question was not clear in detail, but I realy can't find a
solution.
I will show you an example from the help browswer to ilustrate my problem.
From:
To: mathgroup at smc.vnet.net
data={{1.0,1.0,.126},{2.0,1.0,.219},{1.0,2.0,.076},{2.0,
2.0,.126},{.1,.0,.186}};
NonlinearRegress[data,
theta1 theta3 x1/(1+theta1 x1+theta2 x2),{x1,x2},{theta1,theta2,theta3},
RegressionReport->BestFitParameters,ShowProgress->True]
I get:
From In[396]:=
Iteration:1 ChiSquared:0.23634239210284666` Parameters:{1.,1.,1.}
(snip snap) 8><
From In[396]:=
Iteration:11 ChiSquared:0.000043552662305849804` \
Parameters:{3.13156,15.1594,0.780051}
Out[396]=
{BestFitParameters\[Rule]{theta1\[Rule]3.13151,theta2\[Rule]15.1594,
theta3\[Rule]0.780062}}
My aim is to get !automaticaly! a list like this:
{{Iteration:1,{1.,1.,1.}},...,{Iteration:11,{3.13156,15.1594,0.780051}},...,}
May be this problem is very easy to solve, but I found only the "Hand
made solution"
of copy and paste - this is not the way I want to use a computer (-;
So if you have any idea how to solve this problem, please give me a hint.
