Title :
Fitting exponentials: an interest in rates
Abstract :
We study efficient algorithms for solving problems with exponentials. In this paper, we investigate the problem of fitting a sum of exponential functions to data. This problem occurs in many real-world situations, but we´ll see that for many data sets, the solution is not well determined.
