ARprediction
对序列建立AR模型，并以概率形式给出预测数列表达。先进行平稳性检验后求取自相关函数，用Y-W法求取模型参数，并应用FPE准则确定阶数，进行预测后，给出概率表达。(AR model for the sequence established, and the probability forecast given in the form of a list. After a smooth first autocorrelation function test strike strike model parameters YW law and apply the criteria to determine the order of FPE, predict, given the probability of expression.)
