英文摘要:
We model non-stationary volume-price distributions with a log-normal distribution and collect the time series of its two parameters. The time series of the two parameters are shown to be stationary and Markov-like and consequently can be modelled with Langevin equations, which are derived directly from their series of values. Having the evolution equations of the log-normal parameters, we reconstruct the statistics of the first moments of volume-price distributions which fit well the empirical data. Finally, the proposed framework is general enough to study other non-stationary stochastic variables in other research fields, namely biology, medicine and geology.

中文摘要:
我们用对数正态分布对非平稳量价分布建模,并收集其两个参数的时间序列。这两个参数的时间序列被证明是平稳的和类马尔可夫的,因此可以用朗之万方程建模,朗之万方程直接从它们的值序列中导出。利用对数正态参数的演化方程,我们重建了与经验数据拟合良好的成交量-价格分布一阶矩的统计量。最后,所提出的框架具有足够的通用性,可以
研究生物学、医学和地质学等其他研究领域中的其他非平稳随机变量。
