By statistical computation we prove that the confluence process of jiangjia ravine obeys the power-law frequency-area distribution 本文通過統(tǒng)計計算得到,蔣家溝泥石流匯流和流量過程在暴發(fā)頻率與泥石流總徑流量上服從負冪律分布。
This paper presents a new sampling method, which is called sampling method by allocating random order to percentiles based on some random simulation problems of statistical computation 摘要該文針對統(tǒng)計計算中的某些隨機模擬問題提出了分位點隨機配序抽樣法。
Image difference operation is applied to video images taken with image capture device, then statistical computation is performed to judge whether there is vehicle violating the regulations, and corresponding measures are taken 由攝像頭獲取的視頻圖像經(jīng)計算機進行圖像差分運算,結(jié)合統(tǒng)計算法由計算機根據(jù)所得數(shù)據(jù)判斷監(jiān)測區(qū)域是否有違章車輛出現(xiàn)并作出相應的處理。
Latent semantic analysis ( lsa ) is a completely automatic theory and method of the acquisition and representation of knowledge, which extracts the contextual-usage meaning of words by statistical computations applied to a large corpus of text 潛在語義分析(latentsemanticanalysis,lsa)是一種用于自動地實現(xiàn)知識提取和表示的理論和方法,它通過對大量的文本集進行統(tǒng)計分析,從中提取出詞語的上下文使用含義。
The statistical software platform with a certain extent of intelligence abstract statistical software, which is used as a powerful tool in the field of statistical computation, can play very important role . good statistical software should have the features described as follow : 1 一個好的統(tǒng)計軟件應該具備以下基本特征:1、擴充性好:要求能夠適應數(shù)理統(tǒng)計科學的不斷發(fā)展,具有較強的適應能力,增加新的統(tǒng)計數(shù)據(jù)類型、新的統(tǒng)計模型簡便、快捷。
In this article, the concept of statistical template based on data was firstly brought forward, which can effectively simulate the entire statistical computation process by recording the information of data structure and analytic method . we make the statistical template as theoretical basis of statistical analysis platform ( sap ) the statistical template can make our sap has the properties described as follow : 1 . good facility the requirement is to have the statistical knowledge, user need n't has any background of computer science and computational mathematics; the time that is used to learn is short 本文通過對一般統(tǒng)計計算過程的分析,提出了以統(tǒng)計數(shù)據(jù)為中心的統(tǒng)計分析模板的概念,該概念以統(tǒng)計字段來描述統(tǒng)計數(shù)據(jù)的數(shù)據(jù)結(jié)構,通過記錄統(tǒng)計數(shù)據(jù)結(jié)構信息及其相應的統(tǒng)計分析計算服務信息的形式在邏輯上有效地模擬了統(tǒng)計計算的全過程,從而為統(tǒng)計軟件平臺構建了一個堅實的理論基礎,使該統(tǒng)計軟件平臺具備了以下特點:1、易于使用概念清晰、使用簡便,作分析工作時使用者無需任何計算機科學和計算數(shù)學背景知識,懂得基本操作即可,學習周期短。
And we use statistical computation and relativity analysis for the first time . so we make the conclusion that the simulation system obeys the power-law frequency-area distribution by improved 2-d ca model . and by relativity analysis we know simulation sequences are long correlative 通過改進的二維沙堆自動機模型的構建和模擬,本文得到了一系列模擬數(shù)據(jù),并在此基礎之上,首次通過統(tǒng)計計算和相關性分析,得到如下結(jié)論:(1)改進的二維沙堆自動機所模擬的系統(tǒng)在沙粒暴發(fā)頻率對暴發(fā)規(guī)模的關系上服從負冪律分布。
