Testing Traffic Flow Models [PDF]
, 2003 The huge number of different traffic flow models available calls for an attempt to classify, simplify and assess those models. In principle, this is simple to accomplish, since the principal algorithms for assigning quality measures such as X 2 are well known. However, due to a lack of publicly available data, a commonly agreed upon benchmark could not

TESTING GARCH-X TYPE MODELS [PDF]
Econometric Theory, 2017 We present novel theory for testing for reduction of GARCH-X type models with an exogenous (X) covariate to standard GARCH type models. To deal with the problems of potential nuisance parameters on the boundary of the parameter space as well as lack of identification under the null, we exploit a noticeable property of specific zero-entries in the ...

A Model-Driven approach for functional test case generation [PDF]
, 2015 Test phase is one of the most critical phases in software engineering life cycle to assure the final system quality. In this context, functional system test cases verify that the system under test fulfills its functional specification.

Empirical likelihood test in a posteriori change-point nonlinear model
, 2014 In this paper, in order to test whether changes have occurred in a nonlinear parametric regression, we propose a nonparametric method based on the empirical likelihood.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Testing model nesting and equivalence. [PDF]
Psychological Methods, 2010 When using existing technology, it can be hard or impossible to determine whether two structural equation models that are being considered may be nested. There is also no routine technology for evaluating whether two very different structural models may be equivalent. A simple nesting and equivalence testing (NET) procedure is proposed that uses random

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

The Error Correction Model as a Test for Cointegration [PDF]
, 2003 In this paper we generate critical values for a test for cointegration based on the joint significance of the levels terms in an error correction equation.

Possible Experimental Test of Continuous Medium Model for Fractal Media
, 2005 We use the fractional integrals to describe fractal media. We consider the fractal media as special ("fractional") continuous media. We discuss the possible experimental testing of the continuous medium model for fractal media that is suggested in Phys ...

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...
