AMFM representations for the characterization of carotid plaque ultrasound Images
(2008)Stroke is the third leading cause of death in the western world and a major cause of disability in adults. The objective of this work was to investigate the use of AMFM representations for the characterization of carotid ...

Conference Object
Cointegration and nonstationarity in the context of multiresolution analysis
(Institute of Physics Publishing, 2011)Cointegration has established itself as a powerful means of projecting out longterm trends from timeseries data in the context of econometrics. Recent work by the current authors has further established that cointegration ...

Conference Object
Comparison of AMFM features with standard features for the classification of surface electromyographic signals
(2010)In this work AMFM features extracted from surface electromyographic (SEMG) signals were compared with standard time and frequency domain features, for the classification of neuromuscular disorders at different force levels. ...

Article
Consistent Testing for Pairwise Dependence in Time Series
(2017)We consider the problem of testing pairwise dependence for stationary time series. For this, we suggest the use of a Box–Ljungtype test statistic that is formed after calculating the distance covariance function among ...

Article
Distribution theory for the studentized mean for long, short, and negative memory time series
(2013)We consider the problem of estimating the variance of the partial sums of a stationary time series that has either long memory, short memory, negative/intermediate memory, or is the firstdifference of such a process. The ...

Article
Dynamic misspecification in nonparametric cointegrating regression
(2012)Linear cointegration is known to have the important property of invariance under temporal translation. The same property is shown not to apply for nonlinear cointegration. The limit properties of the NadarayaWatson (NW) ...

Conference Object
The effects of applying cellsuppression and perturbation to aggregated genetic data
(2012)The key test for confidence in any association discovered within the medical domain is replication testing. That is, the ability of the association to be detected in independent populations. At the same time, in order to ...

Article
Ethnicity as a factor for the estimation of the risk for preeclampsia: A neural network approach
(2010)A large number of feedforward neural structures, both standard multilayer and multislab schemes have been applied to a large data base of pregnant women, aiming at generating a predictor for the risk of preeclampsia ...

Article
A maximum entropy type test of fit
(2011)In this paper, we propose a test of fit based on maximum entropy. The asymptotic distribution of the proposed test statistic is established and a corrected form for small and medium sample sizes is furnished. The performance ...

Conference Object
Neural networks to investigate the effects of smoking and alcohol abuse on the risk for preeclampsia
(2009)Following the application of a large number of neural network schemes that have been applied to a large data base of pregnant women, aiming at generating a predictor for the risk of preeclampsia occurrence at an early ...

Conference Object
Noninvasive trisomy 21 diagnosis using fuzzy cognitive maps
(Springer Verlag, 2016)A fuzzy Diagnostic Decision Support System (DDSS) has been developed, exploiting the possibilities of a specific algorithm which transforms a crisp dataset into fuzzy. The purpose of the developed fuzzy DDSS is the diagnosis ...

Article
Power divergence family of tests for categorical time series models
(2002)A fundamental issue that arises after fitting a regression model is that of testing the goodness of the fit. Our work brings together the power divergence family of goodness of fit tests and regression models for categorical ...

Article
Residualbased block bootstrap for unit root testing
(2003)A nonparametric, residualbased block boostrap procedure is proposed in the context of testing for integrated (unit root) time series. The resampling procedure is based on weak assumptions on the dependence structure of ...

Article
Residualbased block bootstrap for unit root testingAAA
(2003)A nonparametric, residualbased block boostrap procedure is proposed in the context of testing for integrated (unit root) time series. The resampling procedure is based on weak assumptions on the dependence structure of ...

Article
Residualbased rank specification tests for ARGARCH type models
(2015)This paper derives the asymptotic distribution for a number of rankbased and classical residual specification tests in ARGARCH type models. We consider tests for the null hypotheses of no linear and quadratic serial ...

Article
Unit root testing via the stationary bootstrap
(2006)A nonparametric, residualbased stationary bootstrap procedure is proposed for unit root testing in a time series. The procedure generates a pseudoseries which mimics the original, but ensures the presence of a unit root. ...
