摘要

PPROBLEM TO BE SOLVED: To evaluate an error between a predicted value and an actually measured value considering how the error changes in relation to a group of an attribute value of a phenomenon to be observed (for example, time-sequentially). PSOLUTION: A prediction error-evaluating device 10 preliminarily stores error data in a storage device in association with dates. The error data are data which indicate errors between predicted values to power consumption quantities and actually measured values thereof. A statistical processing part 11 makes one part group and a plurality of part groups, which are obtained by shifting the head and end of the part group by prescribed numbers, processing-object groups according to the groups of the dates stored in the storage device. Then, the statistical processing part 11 reads out, for each processing object group, the error data, which correspond to the dates included in the processing-object groups, from the storage device. The statistical processing part 11 computes, for each processing-object group, the averages or distributions of the error data thus read out, and finds the approximation curves of the distributions of the errors on the basis of the averages and the distributions. A result-outputting part 12 displays the approximation curves on a screen. PCOPYRIGHT: (C)2011,JPO&INPIT

要解决的问题：考虑到误差相对于要观察的现象的一组属性值如何变化（例如，按时间顺序），以评估预测值和实际测量值之间的误差。

解决方案：预测误差评估装置10将误差数据与日期相关联地预先存储在存储装置中。误差数据是表示预测值与功耗量之间的误差和实际测量值之间的误差的数据。统计处理部11根据存储在存储装置中的日期的组，将一个部件组和多个部件组作为处理对象组，该部件组和部件组通过将部件组的前端和末端移动规定的数量而获得。然后，统计处理部11针对每个处理对象组从存储装置中读出与包括在处理对象组中的日期相对应的错误数据。统计处理部分11针对每个处理对象组计算由此读出的误差数据的平均值或分布，并且基于平均值和分布来找到误差分布的近似曲线。结果输出部12在屏幕上显示近似曲线。
