Save guides, add subjects and pick up where you left off with your BBC account. Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three ...

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

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 ...

Euclid discussed the solutions of linear and quadratic equations in geometric terms in his Elements, but there were no further advances for 1,000 years.
