Classification of regression lines
The field of classification and allocation has a vast literature and many applications (Hand, 1997). Usual classification techniques are used for making descriptive clusters that consist of the similar objects which have in one sense common future vectors; then objects are basically represented the points in the d-dimensional future space. For example, the future vector is made up of such as se...
متن کاملGeometric Constructions Relating Various Lines of Regression
As a direct consequence of the Galton-Pearson-McCartin Theorem [10, Theorem 2], the concentration ellipse provides a unifying thread to the Euclidean construction of various lines of regression. These include lines of coordinate regression [7], orthogonal regression [13], λ-regression [8] and (λ, μ)-regression [9] whose geometric constructions are afforded a unified treatment in the present pap...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولRegression lines in chronic kidney disease.
Chronic kidney disease (CKD) has been recognized for millennia. The great physicians Rhazes (865–925 AD) and Abu Sina (aka Avicenna, 980–1037 AD) in ancient Persia described kidney diseases in detail. In medieval times, the pisse prophets predicted outcomes for patients on the basis of uroscopy analyses. Categorization of CKD developed in the 20 century from the nonspecific “Bright’s disease” w...
متن کاملStraightening warped text lines using polynomial regression
Perspective distortion always occurs while scanning thick, bound documents, resulting in two problems in the scanned grayscale image – (i) shade along the ‘spine’ of the book, and (ii) warping of words in the shade area. We proposed a restoration system to solve these two problems in our previous paper [1]. However the shape of the warped words was not fully restored, since we simply shifted an...
