• Resumen

  • There are uncorrelated positive data with multiple least-squares exponential curves that are closer to the data than the horizontal least-squares line is. Also, for some increasing convex positive data, with positive first and non-negative second differences, computations may yield multiple increasing convex positive least-squares exponential curves.
