WebOct 6, 2024 · There is another concept in polynomials called the order, The order of the polynomial is denoted by n. It is the highest coefficient in the mathematical expression for example: Polynomial equation 01 above, is a nth order polynomial regression Polynomial equation 02 above, is a third order/degree polynomial regression WebRunge's phenomenon: high order polynomials can be highly oscillatory. If a curve runs through two points A and B, it would be expected that the curve would run somewhat near the midpoint of A and B, as well. This may not happen with high-order polynomial curves; they may even have values that are very large in positive or negative magnitude.
