Polynomial and rational function modeling : ウィキペディア英語版 | Polynomial and rational function modeling In statistical modeling (especially process modeling), polynomial functions and rational functions are sometimes used as an empirical technique for curve fitting. ==Polynomial function models== (詳細はpolynomial function is one that has the form : where ''n'' is a non-negative integer that defines the degree of the polynomial. A polynomial with a degree of 0 is simply a constant function; with a degree of 1 is a line; with a degree of 2 is a quadratic; with a degree of 3 is a cubic, and so on. Historically, polynomial models are among the most frequently used empirical models for curve fitting.
