ARMA时间序列模型预测风电场风功率大小，matlab源代码特例分析(ARMA time series models to predict the size of wind farm wind power, matlab source code for exception analysi)

本实验设计了一个《北京、南京、深圳列车查询系统》的图形用户界面。用户可以通过此界面，采用“按车站名称查询”、“按列车车次查询”和“按出发地—目的地查询”三种方式，方便地查询需要的列车信息。界面友好清新，操作方便。(The experimental design was a " Beijing, Nanjing, Shenzhen Train Enquiry System," the graphical user interface. Users can use this interface, a " query by station name" , " Query by Train Train" and " by origin- destination query" three ways to easily check in need train information. Fresh and friendly interface, easy to operate.)

这是一个火车票分配问题（只有X是未知的） 假设初始座位数为N 分配给AB，BC，AC的座位数量为（xAB,xBC,xAC） 假设在时间t还剩余的A-B,B-C的可售座位数为（a,b） 三个区段的需求DAB,DBC,DAC,是独立的随机变量（也可以给确定的值），其价格分别为（fAB，fBC，fAC）(This is a train ticket assignment problem (only X is unknown). Suppose the initial number of seats is N The number of seats allocated to AB, BC and AC is (xAB, xBC, xAC). Assuming that the remaining A-B in time t remains, the number of seats available for sale is B-C (a, b). Demand DAB, DBC and DAC in three sectors are independent random variables (which can also be given a fixed value), and their prices are (fAB, fBC, fAC) respectively.)

Chi Square Test for Independence: calculuate the chi square of a vector and the critical value.(Chi Square Test for Independence : calculuate the chi square of a vector and the Kearns Dept.of value.)
