摘要
在运用数理统计方法分析实际数据的基础上,结合国内外的已有研究结果,初步认为在自行车流量小的情况下,泊松分布比较适用于描述自行车到达量的统计分布;而当自行车流量很大时,负二项分布比较适合描述一定条件下的自行车到达量的统计分布.考虑到自行车到达分布的复杂性,文中借鉴知识推理的一些概念和方法,非精确地描述了自行车到达分布规律.
Using statistic methods, and on the results of home and abroad Research, the paper think that poson distribution Is found to be best representative for arrival distribution of bicycles whose volumes is small, and negative Distribution is for arrival distribution of bicycles whose volumes is large. Considering complexity of arrival distribution of bicycles, using some concepts and methods, the paper describe the laws of arrival distribution of bicycles in quality.
