On the asymptotic behavior of general projection-pursuit estimators under the common principal components model
(Elsevier Science, 2010-02)
The common principal components model for several groups of multivariate observations assumes equal principal axes among the groups. Robust estimators can be defined replacing the sample variance by a robust dispersion ...
Consistency of a numerical approximation to the first principal component projection pursuit estimator
(Elsevier Science, 2014-11)
We generalize to functional data, the approach given by Croux and Ruiz-Gazen (1996) to compute robust projection-pursuit principal direction estimators, allowing also for smoothness in the estimators. Consistency of the ...
A projection pursuit framework for supervised dimension reduction of high dimensional small sample datasets
(ElsevierAmsterdam, 2015-02)
The analysis and interpretation of datasets with large number of features and few examples has remained as a challenging problem in the scientific community, owing to the difficulties associated with the curse-of-the-dim ...

Robust functional principal components: A projection-pursuit approach
(Inst Mathematical Statistics, 2011-12)
In many situations, data are recorded over a period of time and may be regarded as realizations of a stochastic process. In this paper, robust estimators for the principal components are considered by adapting the ...
Robust estimators under a functional common principal components model
(Elsevier Science, 2017-09)
When dealing with several populations of functional data, equality of the covariance operators is often assumed even when seeking for a lower-dimensional approximation to the data. Usually, if this assumption does not hold, ...
Influence function of projection-pursuit principal components for functional data
(Elsevier Inc, 2015-01)
In the finite-dimensional setting, Li and Chen (1985) proposed a method for principal components analysis using projection-pursuit techniques. This procedure was generalized to the functional setting by Bali et al. (2011), ...

THE DECENTRALIZATION OF SCHOOL MANAGEMENT POLICIES IN BRAZIL
(Organizacion Estados Iberoamericanos Educacion Ciencia & Cultura-oei, 2015-09-01)
This paper discusses the process of democratization of education management in Brazil, addressing the historical process, laws and documents that consolidate public policies governing its implementation. Dedicated also to ...
