We study model selection strategies based on penalized empirical loss minimization. We point out a tight relationship between error estimation and data-based complexity penalization: any good error estimate may be converted into a data-based penalty function and the performance of the estimate...

Purpose The purpose of this paper is to investigate the impact of bias error resulted from using Monte Carlo simulation in evaluating the American-style option value. Design/methodology/approach The authors develop an analytical approximation formula to quantify the bias error under the...

This paper analyzes microeconomic production functions of Czech small medium enterprises. We use the data from 2002 to 2005 of thirty manufacturing industries (agriculture and services are not included), each divided into five subgroups according to the number of employees. We employ stochastic...
