Data Driven Computing by the Morphing Fast Fourier Transform Ensemble Kalman Filter in Epidemic Spread Simulations
Data Driven Computing Morphing Fast Fourier Transform Ensemble Kalman Filter Epidemic Spread Simulations
2010/3/11
The FFT EnKF data assimilation method is proposed and applied to a stochastic
cell simulation of an epidemic, based on the S-I-R spread model. The FFT EnKF
combines spatial statistics and ensemble f...
The smooth tests for testing uniformity were introduced
by Neyman [15]. The data driven method of selecting the
number d components in a smooth test for uniformity is discussed,
including the rust-...
DATA-DRIVEN SCORE TEST OF FIT FOR CONDITIONAL DISTRIBUTION IN THE GARCH(l,l) MODEL
GARCH(1,l) model noise distribution efficient score vector score test BIC Schwarz selection rule
2009/9/18
A data-driven score test for a conditional distribution
in the GARCH(1,l) model is proposed. Conditional distribution assumption
is verified by a score test, obtained from nesting the null
density ...
DATA-DRIVEN SCORE TESTS FOR HOMOSCEDASTIC LINEAR REGRESSION MODEL:ASYMPTOTIC RESULTS
Efficient score hypothesis testing data-driven test linear regression selection rule
2009/9/18
We describe and investigate new tests for testing the
validity of a semiparametric random-design linear regression model.
The tests were introduced in Inglot and Ledwina (2006a, b). We repeat
here ...
Data-driven wavelet-Fisz methodology for nonparametric function estimation
Besov spaces exponential inequality heteroscedasticity nonparametric regression variance function
2009/9/16
We propose a wavelet-based technique for the nonparametric estimation of functions contaminated with noise whose mean and variance are linked via a possibly unknown variance function. Our method, term...
A data-driven block thresholding approach to wavelet estimation
Adaptivity Besov body block thresholding James–Stein estimator nonparametric regression Stein’s unbiased risk estimate
2010/3/19
A data-driven block thresholding procedure for wavelet regression
is proposed and its theoretical and numerical properties are investigated.
The procedure empirically chooses the block size and thre...
Local superefficiency of data-driven projection density estimators in continuous time
Density estimation data-driven superefficiency continuous time processes
2009/2/23
We construct a data-driven projection density estimator for continuous time processes. This estimator reaches superoptimal rates over a class F0 of densities that is dense in the family of all possibl...
Data-driven efficient score tests for deconvolution problems
Hypothesis testing statistical inverse problems deconvolution efficient score test model selection data-driven test
2010/4/30
We consider testing statistical hypotheses about densities of
signals in deconvolution models. A new approach to this problem is proposed.
We constructed score tests for the deconvolution with the k...
