I don't have a lot of experience with Maple, but I want to plot some test data and find a least squares curve fitting.
I know how to plot the stuff I want to plot, and how to do basic least square fitting.
However, I have 6 data points to apply least squares on, and I have one additional "fixed" point.
I know the curve will have to become parabolic (And I know how to curve fit to that using LeastSquares), but the problem is that the minimum of that parabola has to go through the fixed point.
I have no idea how to achieve this (if it is at all possible).
BTW, I tried cheating a bit, by adding some weights, but it doesn't quite get me exactly what is require. The graph appears to go through the point, alright, but I it is not at it's minimum there.
LeastSquares(Data5, x, curve = a*x^2+b*x+c, weight = [1000, 1, 1, 1, 1, 1, 1])
(Data5 is the data; first point fixed point, remaining 6 test results)
I hope someone can help me.
Thanks in advance
