The neuropsychology of autism and Asperger's disorder : evidence for or against a shared spectrum
… of differentiating groups. Results from the quadratic discriminant analysis demonstrated that the factor scores derived from the Dean-Woodcock Sensory-Motor Battery significantly differentiated the ASD and nonclinical comparison groups. Factor 1 (Simple Sensory Skills) exhibited the strongest …

Selected topics in statistical discriminant analysis.
… consists of three selected topics in statistical discriminant analysis: dimension reduction, regularization methods, and imputation methods. In Chapter 2 we first derive a new linear dimension-reduction method to determine a low-dimensional hyperplane that preserves or nearly preserves the …

Prediction of mRNA polyadenylation sites in the human genome and Mathematical modeling of alternative polyadenylation
… statistical models has been used, such as linear discriminant analysis, quadratic discriminant analysis, and support vector machine (SVM). Among these, SVM was chosen as the classification algorithm for the prediction of poly(A) sites in this work. A program called polya svm has been developed …

Learning and model-based approaches to improved patient monitoring, assessment and treatment in capnography and procedural sedation
… or screening for respiratory disease. The analysis involves preprocessing, extraction of physiologically based features, and development of ensemble-based classifiers based on quadratic discriminant analysis. We applied these methods to capnograms from 30 normal controls and from 109 …

Classification of Carpiodes Using Fourier Descriptors: A Content Based Image Retrieval Approach
… C.velifer, and C.cyprinus. Classification analysis involves both unsupervised and supervised machine learning algorithms. Fourier Descriptors of the fifteen known landmarks provide for strong classification power on image data. Feature reduction analysis indicates feature reduction is …

Chemical Analysis, Databasing, and Statistical Analysis of Smokeless Powders for Forensic Application
… to agglomerative hierarchical cluster (AHC) analysis, and six distinct classes were identified. Within each class, a single m/z ratio had the highest intensity for the majority of samples, though the m/z ratio was not always unique to the specific class. Based on these observations, a new …
