What is the first step toward finding the area between two curves?
First, you will take the integrals of both curves. Next, you will solve the integrals like you normally would. Finally, you will take the integral from the curve higher on the graph and subtract the integral from the lower integral.
What is the area between the curves?
The area between two curves is the integral of the absolute value of their difference. Wolfram|Alpha can calculate the areas of enclosed regions, bounded regions between intersecting points or regions between specified bounds.
How do you find the area of the curve?
The area under a curve between two points is found out by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a & x = b, integrate y = f(x) between the limits of a and b. This area can be calculated using integration with given limits.
How can I statistically compare two curves ( same x values )?
How can I statistically compare two curves (same X values, Different Y values) without using MATLAB or R. I have 200 points of X and Y values and I want to know if the two curves obtained are different from each other. Join ResearchGate to ask questions, get input, and advance your work.
How to calculate the distance between two curves?
This solution uses a two-dimensional array. The cost would be the distance between two points. The final value of the array DTW [n, m] contains the cumulative distance. DTW is similar to Jacopson’s answer. Frechet distance calculates the farthest that the curves separate.
How can I test for differences among curves fit to three?
But if you are doing many comparisons, you should correct for the multiple comparisons. Divide 0.05 (or whatever overall value you want) by the number of pairs of analyses you are comparing, to come up with a new stricter cut off for declaring a P value to be small enough that you can call the comparison “significant”.
When are curves similar and not so similar?
The curves are similar if the area is small, not so similar if the area is not small. Note that I did not define ‘small’. That was intentional. Then again, you didn’t define ‘similar’. Sometimes area isn’t the best metric.
