Solution
The Lev-Mar algorithm is an iterative process and depends heavily on the initial guess coefficients.
To establish a best initial guess, use the following equation:
y = a * exp(b * x) + c
- Guess "c" by looking at the smallest data point.
- Guess "a" by plugging the y-intercept into the equation.
- Calculate "b" by substituting a known (x,y) point and guesses of "a" and "c" into the equation.
