For a number of statistical applications subjective estimates of some distributional parameters - or even complete densities are needed. The literature agrees that it is wise behaviour to ask only for some quantiles of the distribution; from these, the desired quantities are extracted. Quite a...

Given stationary time series data, we study the problem of finding the best linear combination of a set of lag window spectral density estimators with respect to the mean squared risk. We present an aggregation procedure and prove a sharp oracle inequality for its risk. We also provide...

Purpose – Seeks to present a microeconomic model to analyse theoretically BSC, to develop a simplified model version and to apply it empirically. Design/methodology/approach – The model assumes exponential production and demand functions with constant scale factors and elasticities. It is...
