Background: Various studies have documented age-related changes in cognitive abilities and neural basis. Objectives: To investigate the role of neuropsychological function tests in predicting amnestic mild cognitive impairment in the elderly. Materials & Methods: In this cross-sectional study with a correlational design, the study population included elderly people over 60 years old residing ...

While discriminant function analysis is an inherently Bayesian method, researchers attempting to estimate ancestry in human skeletal samples often follow with the calculation of frequentist-based typicalities for assigning group membership. Such approach problematic because it fails account admixture and variation why individuals may be classifijied as outliers or nonmembers particular groups. T...

The  major  aim  of  this  paper  was  to  investigate  the  validity  of  language  and intelligence  factors  for  classifying  Iranian  English  learners`  writing  performance.

Fifty-six patients with senile dementia of Alzheimer type and 84 normal elderly people were examined by EEG and computed tomography. In discriminant function analysis of the computed tomography indexes the highest discriminant function coefficient was for width of the third ventricle. Using computed tomography, the groups were correctly classified for 84% of the subjects. In discriminant functi...

identification of homogenous watershed sub basins allows generalization of environmental study results. for this purpose, first available data for 27 selected watersheds in north alborz regarding 21 variables including physiographic and climatic characteristics was gathered. the most important factors impacting upon soil erosion and sediment yield were equivalent rectangular length, mean annual...
