摘要
从分析绘制异常型直方图的观测误差出发 ,讨论了直方图区间的模糊化问题 ,给出了计算模糊频数的公式和绘制模糊直方图的方法 ,并结合实例 。
In the course of measuring data processing, the distribution and quality of the surveying data can be approximately described by the histogram. But in the course of drawing histograms, the unusual histograms, e.g. bimodal histogram are often presented. For such unusual situation, people impute to the measuring data itself. Analyzing the measuring data which draws the unusual histogram, this paper discusses the question that the histogram block melts histogram, and provides the formula of calculating the fuzzy frequency and method for drawing the fuzzy histogram. The superiority of the fuzzy histogram is stated.
