Unlike a linear, graph, a quadratic graph has an equation which includes an x squared term.

A quadratic graph is produced when you have an equation of the form y = a x 2 + b x + c, where b and c can be zero but a cannot be zero. All quadratic graphs have a line of symmetry. Positive ...

Asymptotic expansions of the distributions of the linear and the quadratic discriminant functions are derived. The expected misclassification probabilities of these two functions are compared when the ...

For the Gaussian sequence model, we obtain nonasymptotic minimax rates of estimation of the linear, quadratic and the ℓ2-norm functionals on classes of sparse vectors and construct optimal estimators ...
