Choice of Smoothing Parameter for Kernel Type Ridge Estimators in Semiparametric Regression Models

open access: yesRevstat Statistical Journal, 2021
This paper concerns kernel-type ridge estimators of parameters in a semiparametric model. These estimators are a generalization of the well-known Speckman’s approach based on kernel smoothing method. The most important factor in achieving this smoothing

Prediction of macroeconomic variables of Pakistan: Combining classic and artificial network smoothing methods

open access: yesJournal of Open Innovation: Technology, Market and Complexity, 2023
This research concentrates on using neural networks in the modelling and prediction of macroeconomic variables in specific. Macroeconomic predictors are particularly interested in neural networks because of their capacity to predict any linear or non ...

Resistant Nonparametric Smoothing with S-PLUS

open access: yesJournal of Statistical Software, 2004
In this paper we introduce and illustrate the use of an S-PLUS set of functions to fit M-type smoothing splines with the smoothing parameter chosen by a robust criterion (either a robust version of cross-validation or a robust version of Mallows's Cp ...

Estimation of the Smoothing Parameters in the HPMV Filter

open access: yesAnnals of the Alexandru Ioan Cuza University - Mathematics, 2011
We suggest an optimality criterion, for choosing the best smoothing parameters for an extension of the so-called Hodrick-Prescott Multivariate (HPMV) filter. We show that this criterion admits a whole set of optimal smoothing parameters, to which belong the widely used noise-to-signal ratios.

Comparison of Remote Sensing Time-Series Smoothing Methods for Grassland Spring Phenology Extraction on the Qinghai–Tibetan Plateau

open access: yesRemote Sensing, 2020
Accurate evaluation of start of season (SOS) changes is essential to assess the ecosystem’s response to climate change. Smoothing method is an understudied factor that can lead to great uncertainties in SOS extraction, and the applicable situation for ...

Unsupervised estimation of dirichlet smoothing parameters

open access: yesProceedings of the 33rd international ACM SIGIR conference on Research and development in information retrieval, 2010
A standard approach for determining a Dirichlet smoothing parameter is to choose a value which maximizes a retrieval performance metric using training data consisting of queries and relevance judgments. There are, however, situations where training data does not exist or the queries and relevance judgments do not reflect typical user information needs ...
