The situation is as follows:
I performed necessary measurements and used them to create two graphs.
I used polynomial regression to find the point of intersection.
What I know:
precision of instruments (absolute error of X and Y values of the points belonging to the graphs).
polynomial regression equations and coefficients of determination.
What I need to find out:
- uncertainty of X and Y values of the intersection point.
In case something sounds unclear (English obviously isn't my native language) - I basically need to do something similar to this (but with polynomial regression)
The question is: what methods should be used to accomplish it?
