Hey there,
the implemented regession-models work fine.
But as a physics teacher I need some more options:
Two are shown here:
linear-model:
y=m*x+n is implemented generally
I need the possibility to set n or m (e.g. n=0) and get the equation of the best line in this case.
sinus:
y=a*sin(b*x+c)+d is implemented generally
I need the possibility to set e.g. d=0 and get the equation under this condition.
The determination of those limiting conditions would be great in every model. 8)

I like this idea 
Does Fit help?
Well, that's what I ment.
But nevertheless it would be really helpful for the pupils, if the special cases of already implemented classes of functions could be easily selected by using check or better input boxes:
e. g. input boxes for all parameters:
class a*sin(bx+c)+ d (or checkboxes for c=0 and d=0)
class a*x+b (or checkboxes for a=0 ? and b=0)
class a*exp(bx+c) + d (or checkboxes for c=0 and d=0)
