A nonlinear equation is an equation that had a degree of 2 or more than two of a variable. The standard form of a nonlinear equation is ax² + by² = c, where a, b, c are constants and x and y are variables. A non-linear equation in a graph represents a curve and has a ...
,n. In equation (3), ε(t) is the same one-step-ahead prediction error in equation (2) and \({\bar{y}}_{i}\) is the temporal average of yi(t) (often equal to zero due to mean centreing) and corresponds to a constant predictor which always predicts y(t) equal to its ...
