In this paper I derive the asymptotics of the exact, Euler, and Milstein MLestimators for diffusion models, including general nonstationary diffusions. Thoughthere have been many estimators for the diffusion model, their asymptotic propertieswere generally unknown. This is especially true for...

We study unrepresentative observational data in survival analysis. The first paper focuses on proportional hazards regressionwhen observed subjects have different selection probabilities. Wedevelop methods which are applicable when the selectionprobabilities are unknown but estimated using...

Cointegration techniques are applied to a model of induced innovation based on the two-stage Constant Elasticity of Substitution (CES) production function. This approach results in direct tests of the inducement hypothesis, which are applied to agricultural data for the United Kingdom from 1953...

The bootstrap is a computationally intensive data analysis technique. It is particularly useful for analysing small datasets, and for estimating the sampling distribution of a statistic when it is intractable. We focus on bootstrap hypothesis testing of linear models. In this context, at...

In 2001, the ACM and IEEE Computing Curriculum stated that it was necessary to address "the need to develop implementation models that are international in scope and could be practiced in universities around the world." With increasing connectivity through the internet, the move towards a global...

This article is devoted to the analysis of dependence of total required financial means of Czech municipalities necessary for solving all current problems based on population, let us say on required CZK per person within the municipalities. This analysis was realized within the research and...
