Bayesian dynamic linear models (DLM) are useful in time series modelling because of the flexibility that they present in obtaining a good forecast. They are based on a decomposition of the relevant factors which explain the behavior of the series through a series of state parameters....

In the present paper we consider the Coefficient of Gini (Kendall and Stuart, 1982), for income distribution. This statistic is derived from data showing the annual taxes paid by the Greek taxpayers, for years 1960 to 1996. An intractable issue is the estimation of its variance because of the...

Resampled Efficiency provides the solution to using uncertain information in portfolio optimization. The proper purpose of investment advice is to improve a client's portfolio in terms of maximizing return for an appropriate level of risk. Asset management techniques for optimizing the...

Dr. Michaud responds to the Fletcher and Hillier article (2001) that compared the performance of mean variance efficient asset allocations to resampled efficient asset allocations by means of a back test

A portfolio-resampling procedure invented by Richard and Robert Michaud is the subject of a highly controversial discussion and big scientific dispute. It has been evaluated in many empirical studies and Monte Carlo experiments. Apart from the contradictory findings, the Michaud approach still...
