Lee, Nelder, and Pawitan (2016) considered the Vascular Cognitive Impairment
(VCI) data. As the elderly population increases, the proportion
of stroke, one of main geriatric diseases also rises. The increase of the
number of patients with stroke results in the rise of that of patients with
the VCI which cognitive function is declined due to stroke. Through an
early intervention for the VCI, the cognitive function can be improved.
They considered standardized VCI scores for four domains (response
variables): executive (y1), memory (y2), visuospatial (y3) and language
(y4). The purpose of the study is to examine the effects of ten demographic
and ten acute neuroimaging variables on the cognitive function
in the ischemic stroke patients.
