PROJECT TOPIC ON A STUDY OF PROPERTIES AND APPLICATIONS OF WEIBULL-BURR XII DISTRIBUTION ABSTRACT

In recent times, lots of efforts have been made to define new probability distributions that cover different aspect of human endeavors with a view to providing alternatives in modeling real data. A five-parameter distribution, called Weibull-Burr XII (Wei-Burr XII) distribution is studied and…

On Akaike's Information Criterion (AIC)

Theory should lead specification and identification of empirical models. However, we often need to compare different, non-nested models. The AIC is particularly useful in this case.

The AIC always seems to be placed in sections for model fit in econometrics books, particularly time-series books. There, the AIC is presented, briefly explained, and, perhaps, compared to the Schwarz Criterion (aka the Bayesian Information Criterion). 

The development of the AIC is actually very interesting, both academically and anecdotally.  The following links to a comment by Akaike on how he came up with the idea; the reference to the original article is also there. (Note to self: commuting might be more productive that you think.)
