Hierarchical cluster analysis and comprehensive evaluation of zizania caduciflora germplasm 茭白資源的系統(tǒng)聚類分析及綜合評(píng)估
Through some specific experiments , we analyse and compare the characters of some discretization methods such as hierarchical clustering analysis , recursive minimal entropy method , and one - rule 通過具體實(shí)驗(yàn),分析和比較了層次聚類法、遞歸最小熵法和one - rule等離散化方法的性能特點(diǎn)。
The distributions of shell flatness and protoconch whorl number are random , we could not find any notable distinction in the shell flatness of snails on surfaces of different inclinations . in a later process , using the three shell factors performed a hierarchical cluster analysis Cathaicacavimargo種群殼扁度和原殼螺層數(shù)的分布是隨機(jī)的,分析結(jié)果中未看到殼扁度事先所估計(jì)那樣水平地面種群貝殼扁平,而垂直巖壁種群貝殼凸起情況。
Based on the two fertility indices , organic matter and total nitrogen , 73 typical soil samples collected from calcareous cultivated soils with different yield levels in 10 counties of henan province were divided into three categories in fertility by hierarchical clustering analysis 本文在河南省十個(gè)縣市不同產(chǎn)量水平的石灰性耕作土壤上采集了73個(gè)典型樣品,并根據(jù)土壤有機(jī)質(zhì)和全氮量這兩個(gè)肥力指標(biāo),用系統(tǒng)聚類的方法將供試土壤劃分為高、中、低三種肥力類型。
Using the data of statistic books , with the help of spss soft , this paper makes a principal components analysis on the comprehensive urbanization development level of 31 provinces in our country , and on basis of it , a hierarchical cluster analysis is made , so the 31 provinces are divided into 5 types , according to the result , the attributes of each type can be concluded , at last i set forward my own suggestion and consideration 摘要本文運(yùn)用統(tǒng)計(jì)年鑒數(shù)據(jù),借助spss統(tǒng)計(jì)分析軟件,對(duì)我國31個(gè)省市的城鎮(zhèn)化綜合發(fā)展水平作主成分分析,并在此基礎(chǔ)上進(jìn)行聚類分析,將31個(gè)省市分為五種類型,根據(jù)分析結(jié)果總結(jié)出各個(gè)類型的特征,得出結(jié)論,最后提出自己的建議和思考。
