A locally adaptive bandwidth selector for kernel based regression
Giordano, Francesco; Parrella, Maria Lucia (2009)The selection of the smoothing parameter represents a crucial step in the local polynomial regression, because of the implications on the consistency of the nonparametric regression estimator and because of the difficulties ... -
A screening selection procedure for nonparametric regression and survival analysis
Milito, Sara (Universita degli studi di Salerno, 2020-05-18)This thesis aims at proposing a new method of solving the nonparametric and non-additive regression problem in presence of ultra-high dimensional data. In this context, there are two relevant aspects: variable selection ... -
Bias-corrected inference for multivariate nonparametric regression: model selection and oracle property
Giordano, Francesco; Parrella, Maria Lucia (2014)The local polynomial estimator is particularly affected by the curse of di- mensionality. So, the potentialities of such a tool become ineffective for large dimensional applications. Motivated by this, we propose a new ... -
GRID for model structure discovering in high dimensional regression
Giordano, Francesco; Lahiri, Soumendra Nath; Parrella, Maria Lucia (2014)Given a nonparametric regression model, we assume that the number of covariates d → ∞ but only some of these covariates are relevant for the model. Our goal is to identify the relevant covariates and to obtain some ... -
High-dimensional statistics for complex data
Pacella, Massimo (Universita degli studi di Salerno, 2018-05-29)High dimensional data analysis has become a popular research topic in the recent years, due to the emergence of various new applications in several fields of sciences underscoring the need for analysing massive data ... -
High-dimensional time series clustering: nonparametric trend estimation
Feo, Giuseppe (Universita degli studi di Salerno, 2021-10-19)The era of big data has produced extensive methodologies for extracting features/patterns from complex time series data. From a data science per- spective these methodologies have emerged from multiple disciplines, ... -
Inferenza non parametrica nel contesto di dati dipendenti: polinomi vocali e verosimiglianza empirica
Monda, Anna (Universita degli studi di Salerno, 2013-03-18)Il presente lavoro si inserisce nel contesto delle più recenti ricerche sugli strumenti di analisi non parametrica ed in particolare analizza l'utilizzo dei Polinomi Locali e della Verosimiglianza Empirica, nel caso di ... -
Parameter estimation in continuous stochastic volatility models
Albano, Giuseppina; Giordano, Francesco; Perna, Cira (2009)Continuous-time di usion processes are often used in literature to model dynamics of nancial markets. In such kinds of models a rel- evant role is played by the variance of the process. So assumptions on the functional ... -
Weak consistent moving block bootstrap estimator for the variance of CLS estimators in a class of bilinear models
Giordano, Francesco (2008)Grahn (1995) introduced the Conditional Least Squares estimators for the class (I) of bilinear models. These estimators have a variance which is difficulty to derive analytically. In this paper we derive the conditions ... -
Weak consistent moving block bootstrap estimator of sampling distribution of CLS estimators in a class of bilinear models
Giordano, Francesco (2005)Grahn, (1995) introduced the Conditional Least Squares estimators for the class (I) of bilinear models. Such estimators have a variance which is difficulty to derive analytically. The aim of the present paper is to ...
