【Abstract】 A multiplicative congruential method uses lengthening and folding operations to generate pseudo random sequences; based on this process,a interval predictive method is presented. This method needn’t determine a specific predictive model, operates fast and applies widely. Computer simulation for some groups of pseudo random sequences generated by a multiplicative congruential method show that this method can predict the pseudo random sequences; furthermore, predictive performance is still very good above some signal noise ratio level.更多还原
