OBJECTIVE We investigated neuropsychological markers that can be used to discriminate pathological cognitive aging from normal cognitive aging. METHODS We administered frontal lobe function tests including the Wisconsin Card Sorting Test (WCST), digit span test, lexical fluency test, fixed condition design fluency test, and Trail Making Test B (TMT-B) to 92 individuals with pathological cogni...

5 × 2 cross-validated F-test based on independent five replications of 2-fold cross-validation is recommended in choosing between two classification learning algorithms. However, the reusing of the same data in a 5 × 2 cross-validation causes the real degree of freedom (DOF) of the test to be lower than the F(10, 5) distribution given by (Neural Comput 11:1885–1892, [1]). This easily leads the ...

During World War I there was much lamentation over the "defects of the draft," and the word "shocking" was in frequent use with reference to the condition of a large proportion of men of military age. When, more recently, it became necessary again for society to interpose a shield of human lives between itself and disaster, its cerebral cells once more became agitated over the report that its y...

BACKGROUND & OBJECTIVES Plasmodium falciparum cerebral malaria remains a major health problem in India. The efficacy of treatment of cerebral malaria lies in its early diagnosis through rapid diagnostic methods. ParaSights-F test detects HRP-2 antigen secreted by parasitised red blood cells and quantitative buffy coat assay (QBC) is examination of buffy coat for the presence of malarial parasit...

Gene selection is an important issue in analyzing multiclass microarray data. Among many proposed selection methods, the traditional ANOVA F test statistic has been employed to identify informative genes for both class prediction (classification) and discovery problems. However, the F test statistic assumes an equal variance. This assumption may not be realistic for gene expression data. This p...

SUMMARY Background. Individual feedback on general practitioners' requests fo r tests can im prove the q u a lity o f th e ir test ordering behaviour. Little is known o f the side effects on hospital referral behaviour when the use o f tests is reduced through feedback. Aim. A study was undertaken to explore changes in general practitioners' hospital referral rates in a region where their use o...
