The author investigated briefly over the expected value of MLE estimate based on standard deviation and expected deviation.

The mathmatical derivation is clear and thourough. However, it would be better for the reader if more context would be there to provide better transition regarding different parts.

The case of maximum likelihood estimation examples for Gaussian R.V. both mu and sigma unknown was investigated and is truely interesting since in real world even if the data come in with Gaussian distribution the parameter is probably still unknown. Biasness of an estimator was also briefly investigaed at the very end.
