查询词典 forecasting

Stock market is a complicated non-linear dynamic system. It is very difficult to open out it's inherent rules using traditionary timing prediction technique. First, I will develop a new method, which is upon the support vector machine, to solve the problem in the aspect of forecasting the stock price.

With consideration of uncertainties in load forecasting, the triangular fuzzy number was used to express the actual load demand of users at a certain time in the future, and a set of optimal time-of-use price design models based on fuzzy demand and users' diverse response were established.

考虑负荷预测的不确定性，运用模糊三角数表示用户未来时刻的实际需求。结合分类用户不同程度的需求价格响应，构建了一套基于模糊需求和用户分类响应程度下的最优分类峰谷分时电价设计模型。

The Markov forecast model, time series method (triple exponential smoothing method and a combined of triple exponential smoothing method and Markov model) and stepwise regression forecast method were choosed, and the basic principles and processes of the three models were analyzed and compared. Based on above, the three methods were used to predict population dynamic of Cricetulus barabansis and Meriones unguiculatus. The characteristic, accuracy and applicability of three methods were analysed and compared. The results showed that,(1) Markov model belongs to a middle-long time forecast model, and the result was interval forecast, but it reached the requirement of forecasting the harmful population dynamic of rodents. Through the forecasted population dynamic of Cricetulus barabansis and Meriones unguiculatus in 2004, the results were accurate; this meant that Markov model was a good forecast model to Cricetulus barabansis and Meriones unguiculatus population.

选择马尔可夫链预测模型、时间序列分析法(三次指数平滑法、三次指数平滑法和马尔可夫链预测模型的组合预测法)和逐步回归预测法，对这三种模型的基本原理、模型的构建过程进行对比分析，在此基础上用此三种方法预测了黑线仓鼠和长爪沙鼠的种群数量，并对三种方法的特点、预测的准确度和适用范围进行了比较分析，结果表明：(1)马尔可夫链预测模型属于中长期预测，预测的结果为区间预测，但对于害鼠种群数量的预测来说已经达到要求，通过对2004年黑线仓鼠和长爪沙鼠种群数量的预测，预测的结果都比较准确，这说明对于预测黑线仓鼠和长爪沙鼠种群的数量动态，马尔可夫链模型是比较好的模型。
