mlburr | R Documentation |
The maximum likelihood estimator fails to exist when the data contains no values strictly smaller than 1. Then the likelihood converges to the likelihood of the Pareto distribution in this case.

This function estimates the only the shape parameters of the Burr distribution. The shape is set to 1.
For the density function of the Burr distribution see Burr.
