Nonparametric model is a reasonable alternative to the conventional binormal model when degenerate data sets occur or when the sample size of continuous data is large.

In this research, the SOLO (Structure of the Observed Learning Outcome) Taxonomy presented by Australian scholars Biggs and Collis (1982) was adopted, and students studying the fifth and sixth grades in Taipei area were chosen as research targets.This study was primarily implemented with a quantitative analysis and supported by a qualitative analysis. In order to carry out the research, a questionnaire had been designed with criteria suggested by Jones et al.(2000), including "describing data","organizing and reducing data","representing data" and "analyzing and interpreting data." This questionnaire consisted of open-ended questions, and after analyzed with qualitative methods, the responses were classified and scored based on standards set in SOLO Taxonomy. Then the quantitative method "Partial Credit Analysis" from Rasch model was adopted in examining the reliability, validity and consistency of outcomes from the qualitative analysis.

提出的统计思维架构-「描述资料」、「组织及简化资料」、「呈现资料」、「分析资料」作为评量试题的向度,题型为开放性问答题,在区分学童的答题表现方面,采用质的分析,参照SOLO(Structure of the Observed Learning Outcome)分类法的分类标准,将学童不同的答题反应进行分类,给予不同的分数,最后再采用Rasch model中的部份给分模式进行量化分析,以量化数据佐证质性分析的信度与效度,以及不同给分的吻合度。

If outcome is continuous, it makes no statistical sense to dichotomize it.

如果结果是连续的,那么使其变成二分类资料是没有统计必要的

For organizing vegetation submodel, started with the bottom-up gateway to agglomerate plot-data. The vegetation types must be confirmed before predictive vegetation mapping, therefore designed a transforming program to combine 585 plot-data from different surveys for the purpose. But the result of the classification and ordination of the combined plot-data couldn't display comprehensive vegetation types of Taiwan, because the plots were insufficient and disproportionate. Consequently, this study adopted the top-down gateway to divisive vegetation. After referring to Taiwan and east-Asia vegetation research papers and American national vegetation classification system etc., the physiognomic classification scheme of Taiwan had been drafted as vegetation submodel. The scheme included 4 levels: 2 classes, 5subclasses (subarctic, coldtemperate, cooltemperate, warmtemperate, subtropical), 8 groups (based on phenology and types of predominant leaf) and 16 formations (based on moisture regime and predominant taxa). And, the scheme dealt completely with the diverse nomenclatures of vegetation types in the past.

为建立植群亚模型,首先依「整合大量样区资料,由下而上的低阶植相聚类」之途径,设计建档程序及转档程式,成功整并不同来源之585个样区资料,但因样区数目不足且分布不均,分析结果未能显示出台湾完整的植群类型;故转循「预先设定植群类型,由上而下的高阶形相分类」之途径,经参考他国植群分类系统及台湾、东亚植群分类研究报告,订定分类原则及架构,提出4阶层之潜在植群形相分类方案:(1)寒原、森林2类群系纲;(2)亚寒带、冷温带、凉温带、暖温带、亚热带5类群系亚纲;(3) 8类群系组表徵优势植群之叶片的物候与形态;(4) 16类群系说明其水分境制及优势分类群;此方案统一处理了过去各种有关植群划分之纷岐名制,方案之各阶植群类型亦即本研究之植群亚模型。

In a database the concept of an example might change along with time which is known as concept drift When the concept drift the classification model built by use of old data is unsuitable for classify new data Therefore concept drift has become a hot issue in data mining in recent years Although many algorithms had been proposed to resolve this problem they can not provide users with the reason of concept drift However a user might be very interested in such rules For example doctors want to find what makes disease change; researchers want to know the reason of the variety of the weather; and decision makers would like to understand why a customer's shopping habit change In this thesis we propose a Concept Drift Rule mining Tree called CDR-Tree to solve this problem CDR-Tree can not only find the rule of concept drift also build the prediction model for both old and new data at the same time

无论在大型资料库或现实生活中,同一资料样本的概念有可能会随著时间的递移而改变,也就是产生所谓的概念漂移。当样本发生概念漂移时,由旧有资料所建构的分类模组将不再适用於预测新获得的资料,因此,近年来概念漂移已成为资料探勘中一项热门的研究议题。虽然已有?多学者提出不同的技术来解决概念漂移的问题,但是这些方法都是利用修正或重建的方式来产生适合新资料的预测模组,并无法提供造成概念漂移的原因。然而对使用者而言,其感兴趣的可能正是这些引起概念漂移的规则,如医生可能想了解引起疾病变化的主因、学者会想要知道气候转变的规则、或是决策者想找出顾客购物习惯改变的因素等。因此,本论文提出概念漂移规则探勘树( Concept Drift Rule mining Tree ),简称CDR-Tree,来解决这个问题。CDR-Tree不但能探测出造成概念漂移的主要原因,亦能同时建立新旧资料的预测模组以供决策者运用使用。
