Hi all. I have estimated the points of a cumulative distribution and I want
to add to the scatterplot the power-law and truncated power-law curves that
best fit the data. My code already plots everything nicely, except the
fitted curves (I'm a beginner, so it took me ages). My question is very
simple. How can I find the best fit curves and add them to the plot?
Thanks for your help.

There are a lot of possibilities. One method is to fit using nonlinear
least squares using nls_estimate in the Octave Forge econometrics
package. nls_example in the same package shows how to do it.
