| description | The invention discloses a price calculation method and system based on a large sample. The system comprises the steps of obtaining equipment material prices and the frequency of occurrence of the same equipment material price, establishing a statistical window by taking the equipment material price with the highest frequency as a window center, and calculating a price statistical value of the statistical window to obtain an equipment material release price. According to the method, under the condition that the data sample is large enough, the information price prediction release of the equipment material price is perfected based on the normal distribution conforming to the equipment material price distribution, the representativeness is higher, and the influence of random variables on the overall level of the price is eliminated.
本发明公开了一种基于大样本的价格测算方法及系统。该系统包括：获取设备材料价格以及同一设备材料价格出现的频数，以所述频数最高的所述设备材料价格为窗口中心，建立统计窗口，计算所述统计窗口的价格统计值，得到设备材料发布价格。本发明在数据样本足够大的情况下，基于设备材料价格分布所符合的正态分布，完善了设备材料价格的信息价预测发布，代表性更强，剔除了随机变量对价格整体水平 |
