    Robust variable selection through MAVE

    No full text
    Dimension reduction and variable selection play important roles in high dimensional data analysis. The sparse MAVE, a model-free variable selection method, is a nice combination of shrinkage estimation, Lasso, and an effective dimension reduction method, MAVE (minimum average variance estimation). However, it is not robust to outliers in the dependent variable because of the use of least-squares criterion. A robust variable selection method based on sparse MAVE is developed, together with an efficient estimation algorithm to enhance its practical applicability. In addition, a robust cross-validation is also proposed to select the structural dimension. The effectiveness of the new approach is verified through simulation studies and a real data analysis

    Diplomová práce popisuje návrh řešení personální situace v centru klinických hodnocení CTCenter MaVe s. r. o. Práce byla rozdělena na část teoretickou a praktickou, přičemž teoretická část se věnuje problematice personálního řízení a specifikům personálního řízení ve zdravotnictví. Praktická část analyzuje prostředí organizace. Na základě analýz a zejména personální analýzy byl navržen systém opatření k zavedení optimálního personálního obsazení centra. Centrum klinických hodnocení je velice specifickým typem zdravotnického zařízení, proto muselo být i při tvorbě tohoto projektu postupováno ne zcela obvyklým způsobem. Projekt byl navržen společnosti k zavedení jako efektivní a funkční.The thesis describes a solution design of personnel situation in the clinical trials center CTCenter MaVe s. r. o. The thesis is divided into theoretical and practical sections. While the theoretical part deals with the personnel management and with specifics of personal management in the healthcare, practical section analyzes the environment of the organisa-tion. On the basis of this analysis especially analysis of the personnel situation a system of measures to be implemented for achievement of optimal personnel staffing was suggest-ed. The clinical trials centre is a very specific type of medical facility therefore the project itself had to be carried out in an uncommon manner. The project was suggested to the company for implementation as effective and functional.Ústav managementu a marketing

This is an open-access article distributed under the terms and conditions of the Creative Commons Attribution license (http://creativecommons.org/licenses/by/3.0/).The single-index (SI) regression and single-index quantile (SIQ) estimation methods product linear combinations of all the original predictors. However, it is possible that there are many unimportant predictors within the original predictors. Thus, the precision of parameter estimation as well as the accuracy of prediction will be effected by the existence of those unimportant predictors when the previous methods are used. In this article, an extension of the SIQ method of Wu et al. (2010) has been proposed, which considers Lasso and Adaptive Lasso for estimation and variable selection. Computational algorithms have been developed in order to calculate the penalized SIQ estimates. A simulation study and a real data application have been used to assess the performance of the methods under consideration

    Clustering in dimension reduction for function approximation problem

    No full text
    In order to reduce the dimension of input vectors before construction of ap-proximation MAVE-type methods (minimum average variance estimation) can be used, however they are very computationally intensive. In the present work the modification of method MAVE is described which allows substantial decrease of algorithm run time at the expense of small error increase
