Application of Discriminant Function Analysis in ischemic stroke group level discrimination

This paper presents the application of Discriminant Function Analysis (DFA) of stroke brainwave for ischemic stroke group level discrimination. The Relative Power Ratio (RPR) of stroke brainwave has been selected as an input for DFA. There were 100 subjects from National Stroke Association of Malaysia (NASAM), Petaling Jaya, Selangor, Malaysia divided into Advance Group (AG), Intermediate Group (IG) and Early Group (EG)with 33, 36 and 31 subjects for each group. The characteristic of the acute ischemic stroke brainwaves were determined due to the group rehabilitation progression. From the results, it shows that this technique can be classifying the three different stroke group levels with minimum of 72%, 61% 59.5% and 81% for accuracy, precision, sensitivity, specifity respectively.
