Introduction Multi-canal benign paroxysmal positional vertigo is considered to be a rare and controversial type in the new diagnostic guidelines of Bárány because the nystagmus is more complicated or atypical, which is worthy of further study. Obje

Publikováno v: Journal of Magnetic Resonance Imaging. 56:291-300

Chronic unilateral vestibulopathy (CUVP) is often accompanied by dizziness and postural instability, which restrict patients' daily activities. It is important to understand central compensation mechanisms underlying these symptoms in patients with C

Automatic search intervals for the smoothing parameter in penalized splines

Autor: Zheyuan Li, Jiguo Cao

Publikováno v: Statistics and computing. 33(1)

The selection of smoothing parameter is central to the estimation of penalized splines. The best value of the smoothing parameter is often the one that optimizes a smoothness selection criterion, such as generalized cross-validation error (GCV) and r
