Hello everyone. I'm trying to model a curve that looks something like the attached file when plotted with a logarithmic x axis. And something like a parabola(not exactly. I tried a parabolic function for this but it didn't work) when plotted with linear x axis.
Can someone guide me regarding what kind of function would look like the attached curves?
I'd suggest a GAM ( generalized additive model). which will fit almost anything. A Google search will get you started..Best wishes David Booth
Respected Sir Dauji Saha
,I have tried it for myself with various exponential, parabolic and other functions and got an okay-ish result which could possibly be applied to practical applications however I was trying to find a method which would give me a much more exact result.
I agree with your point and hence am trying more methods myself as well.
Thank you for the feedback.
David Eugene Booth Thank you sir for a nice idea. I have personally never done this before. I will try and see if it gives a better result in a simple expression. Thank you very much.
Dear Venkatesh Jayanti ,
welcome!
I see that NA is proportional to exp T/Tc where Tc is a characteristic temperatures Tc that changes with the NA level.
This vision may help you find a more compact formula for your curve.
You can also try log -log plot it may result in a simpler relation.
Best wishes
It could be a rational function, but you should start with the theoretical relationship between the variables. Can you tell me more about that?
Koen Van de Moortel Sir the theoretical relationship between the variables is extremely complex mathematically. And this graph can be only calculated by numerical calculations.
Venkatesh Jayanti If you know what it is, can't you calculate a Taylor approximation?
