英文摘要：
  This work is devoted to the study of modeling geophysical and financial time series. A class of volatility models with time-varying parameters is presented to forecast the volatility of time series in a stationary environment. The modeling of stationary time series with consistent properties facilitates prediction with much certainty. Using the GARCH and stochastic volatility model, we forecast one-step-ahead suggested volatility with +/- 2 standard prediction errors, which is enacted via Maximum Likelihood Estimation. We compare the stochastic volatility model relying on the filtering technique as used in the conditional volatility with the GARCH model. We conclude that the stochastic volatility is a better forecasting tool than GARCH (1, 1), since it is less conditioned by autoregressive past information.

中文摘要：
这项工作致力于地球物理和金融时间序列建模的研究。提出了一类具有时变参数的波动率模型来预测平稳环境下时间序列的波动率。具有一致性质的平稳时间序列的建模有助于更确定的预测。利用GARCH和随机波动率模型，我们预测了一步领先的建议波动率，标准预测误差为+/-2，这是通过最大似然估计实现的。我们将条件波动率中使用的基于过滤技术的随机波动率模型与GARCH模型进行了比较。我们得出结论，随机波动率是一种比GARCH（1，1）更好的预测工具，因为它不受自回归过去信息的制约。
