代码说明:

  SkewT分布是近年来得到广泛使用的一种参数化分布。区别于传统的正太分布、学生-t分布,SkewT分布除了具有厚伟特征之外,还引入了偏斜特征。该分布对于金融领域的研究与应用具有十分重要的价值。当然,也是一个重要的统计工具。SkewT分布由Bruce E. Hansen(1994)构造,本源码包括SkewT分布的密度函数、累计概率、随机数生成、理论矩。(SkewT distribution has been widely used recently. Different from traditional Normality and Student-t distribution, SkewT parameterizes both tail-thickness and skewness. SkewT is valuable to financial applications and studies, and other statistic tool. SkewT is firstly introduced by Bruce E. Hansen(1994). This package includes M files on the density of SkewT, CDF, random number generator and theoretical moments of SkewT.)

  • 小波神经网络的时间序列预测-短时交通流量预测
    本文采用小波神经网络进行交通流量预测,短时交通流量存在随机性和非线性因素,影响预测的准确性。传统预测模型难以反映交通流量变化特点,同时传统神经网络易陷入局部极小值,泛化能力差,交通流量预测精度低。为了提高短时交通流量预测精度,提出一种小波神经网络的短时交通流量预测模型。小波神经网络可以对短时交通流量随机性、不确定性进行局部分析,并进行非线性预测,验证了模型的有效性,进行了对比试验。验证结果表明,小波神经网络提高了短时交通流量预精度,预测结果更具应用价值。(In this paper, wavelet neural network is used to forecast traffic flow. There are random and nonlinear factors in short-term traffic flow, affecting the accuracy of prediction. The traditional prediction model is difficult to reflect the characteristics of traffic flow changes. At the same time, the traditional neural network is easy to fall into the local minimum, the generalization ability is poor, and the prediction accuracy of traffic flow is low. In order to improve the accuracy of short-term traffic flow forecasting, a short-term traffic flow prediction model based on wavelet neural network is proposed. The wavelet neural network can analyze the randomness and uncertainty of short-term traffic flow and perform nonlinear prediction. The validity of the model is verified and a comparative experiment is conducted. The verification results show that the wavelet neural network improves the short-term traffic flow pre-precision, and the prediction result has more application value.)
