missing values 中文意思是什麼
missing values
解釋
缺失值-
If the report included query - based or expression - based parameters, updating a single parameter property usually meant you had to republish the report. failure to republish the report resulted in reports that were missing query - based default values after a parameter property was changed
如果報表包括基於查詢或基於表達式的參數，則更新單個參數屬性通常意味著必須重新發布該報表，否則，將導致報表在參數屬性更改之後丟失基於查詢的默認值。 -
Filling missing values, smoothing noise data and removing inconsistent data are all adopted to gain high quality data

The essential idea was that an incomplete data set including missing values was partitioned into several fuzzy clusters by using local principle component with least variance, and through solving the general inverse matrix of the data to obtain the principle components of each sub - clusters, the missing values in clusters could be estimated based on local principal components utilizing a simple linear model
其基本思想是，先利用具有最小方差的局部主成分，把包含有遺漏值的不完備數據集劃分成多個模糊聚類，然後通過求解廣義逆矩陣來獲得各個子聚類的主成分，最終在局部主成分的基礎上通過簡單的線性方程模型去佑計聚類中的遺漏值。 -
Then the thesis further analyses some core techniques including the system of database, data warehouse and data mining and so on, and presents the frame of function of bank crm. the thesis puts its emphasis on the research on the data preprocessing of data warehouse, data copying, data cleansing, data integration and quality verifying included. finally the thesis discusses the key technology of data warehouse in bank crm - the cleansing of data of customers, and presents some methods of cleansing aiming at noisy values, missing values, conflicting values and duplicated values
本文在充分分析銀行crm的需求的基礎上，提出了基於數據倉庫的銀行crm系統的體系結構，並進一步分析了該體系結構中客戶數據庫系統、數據倉庫、數據挖掘等核心技術組件的內涵，給出了銀行crm系統的功能構架；重點研究了銀行業務系統多年積累的客戶數據向數據倉庫遷移的預處理方法和過程，其過程包括數據復制、數據清洗轉換、數據集成、質量檢驗和數據裝載；最後討論了銀行crm系統應用數據倉庫的關鍵技術：客戶數據清洗，給出了針對噪聲數據、空缺數據、不一致數據和重復數據的清洗方法。 -
The seasonal kendall test overcomes a number of problems that can commonly skew the results of long - term studies, such as non - normal data, missing values, seasonality and serial dependence where data is dependent on other data
這種方法可克服多種分析長期性數據所出現的問題，例如不正常數據數值缺失季節變化和數據相依某類數據依賴其他數據等因素。 -
If there is no physical test resource, the system copies all of its values from the component, and you need to fill in the missing necessary properties manually in the
如果沒有物理測試資源，系統將從組件復制它的所有值，然後您需要在 -
5. data preparation is essential procedure before data mining, and the thesis presents two algorithms for the filling of missing values and the finding of duplicates, two of data problems in data preparation. at first, the thesis uses of rough analysis to predict the missing values with known values to solve the problem of missing values, and the results are with higher accuracy ; then the thesis uses partition data table and quick sort method to find duplicates, which can decrease the searching time for finding
數據預處理是數據挖掘之前的必要準備步驟，針對數據預處理問題中的缺失數據與重復數據的挖掘問題提出兩種演算法，首先針對缺失數據問題，浙江大學博士學位論文利用rough集理論通過對己知數據進行預測實現對缺失數據的填補，達到了一定的預測精度;然後針對重復數據問題，利用數據表分解技術以及快速排序方法實現重復數據的發現，並降低了重復數據的發現時間。 -
This problem may be compounded by applications that use values such as 00 or 99 as “ missing ” value indicators
有些應用程序用諸如00或99之類的數字來表示空值的時候可能遇到這個問題。 -
