A general method of integrating Ordinary Differential Equations. It proceeds by extrapolating a polynomial fit to the derivative from the previous points to the new point (the predictor step), then using this to interpolate the derivative (the corrector step). Press et al. (1992) opine that predictor-corrector methods have been largely supplanted by the Bulirsch-Stoer and Runge-Kutta Methods, but predictor-corrector schemes are still in common use.
