029 Notes: ***, ** and * indicate the rejection of the null hypothesis of unit root at 1%, 5% and 10% level of Significance respectively, for the ADF, DF-GLS and NP tests.
The ADF, DF-GLS and NP test the null of unit root whereas the KPSS tests the null of stationarity.
In CHARTER participants with incidental or contributing conditions, the researchers vised standard NP tests
to determine whether they had asymptomatic neurocognitive impairment (impairment that did not interfere significantly with everyday functioning), mild neurocognitive disorder, or HIV-associated dementia.
are routinely performed in the central laboratory.
Traditional NP tests have been validated for many years, but application to large groups is limited by the time required to perform baseline testing.
The NP test results may be factored into deciding on return to play, although it has not been conclusively demonstrated that NP testing, used in isolation, is an appropriate way to decide when an athlete is safe to return to competition.
Recent data has raised significant questions about the relative importance of LOC as a predictor for concussion severity and outcome (as measured by NP test scores).
On the basis of this evidence, it can only be concluded that a) VCS abnormalities are so widespread and nonspecific as to have limited usefulness as a biomarker for any particular condition (especially in the absence of industrial hygiene or environmental documentation regarding the source of exposure); and b) there is no evidence that VCS deficits have been observed in persons with current active PEAS verified by accepted, objective NP tests
In order to achieve these real-world conditions, TERAGO is leveraging the deep functionality of Spirent's AX/4000 platform, which helped them establish a complete suite of 10 Gigabit NP tests
