pm_estimate
利用周期图法对序列的功率谱进行估计。数据窗采用汉明窗。假设在白噪声中分辨这三个不同频率的正弦信号,其相位是均匀分布在2PI的独立随机变量,而 是一个单位白噪声.生成50个长度为N=512的 的样本序列集合。
(use map cycle sequencing method of the power spectrum estimation. Data window using Hamming window. Assume that the white noise to differentiate between the three different frequency sinusoidal signal, its phase is uniformly distributed in the PI two independent random variables. but a flat white noise. Generating 50 length N = 512 samples of the sequence set.)

说明： 使用个股日内髙频收益率计算己实现值进行分析,同时计算得到二阶矩
和高阶矩值并进行对比。本文根据己实现量的大小将所有样本股分为己实现值由
小到大的姐别,分别跟踪各股票组合的收益,探索预期收益与个股己实现值之间
的变化关系,然后将分组的结果应用于多空策略,为提高资产配置收益提供参考。
同时,将各己实现变量和各类对预期收益产生影响的控制变量放在一起构建
Fama-MacBeth截面回归,分析高频已实现量是否具有定价能力。(The realized value is calculated by using the daily gust rate of return of individual stocks, and the second-order moments are obtained by calculating at the same time.
Comparisons are made with higher order moment values. This paper divides all sample stocks into realized values according to the size of realized stocks.
Sisters from small to large track the earnings of each stock portfolio, and explore the relationship between expected earnings and the realized value of each stock.
Then the grouping results are applied to the multi-empty strategy to provide reference for improving asset allocation returns.)
