On convergence of LAD estimates in autoregression with infinite variance
, 1982 The least absolute deviation estimates L(N), from N data points, of the autoregressive constants a = (a1, …, aq)′ for a stationary autoregressive model, are shown to have the property that Nσ(L(N) − a) converge to zero in probability, for σ < 1α, where ...

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

Wind-profile measurements above a maize crop
, 1978 An experiment of wind-profile measurements above a maize crop was described. First the mean ratio between the height of the adapted layer and the fetch was deduced from profile measurements at several positions in the field.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Focal cortical dysplasia (FCD) is the most common etiology of drug‐resistant epilepsy in children. Focal to bilateral tonic–clonic seizures (FBTCS) mark a high risk of drug‐resistant epilepsy and involve thalamocortical circuitry in their generation and propagation.

A contribution to adaptive robust estimation
, 1981 Includes bibliography.This study initially set out to consider the possibility of constructing an adaptive robust estimation procedure for the standard linear regression model when the disturbance vector deviated from normality, however, after the ...

Arthritis Care &Research, EarlyView.Objective Frailty occurs prematurely in rheumatoid arthritis (RA) and is associated with poor health outcomes. We compared the performance of four frailty instruments, including a pragmatic alternative measure using chair sit‐to‐stand (STS), and evaluated their abilities to predict poor health outcomes.
