QuickEdit 讓您可輕易讀取 STDF 檔中的所有資料。各部份參數彙總、軟體二進制結果、硬體二進制結果、實驗參數資料,都以直覺性的表格方式呈現。您可以將結果另外輸出成 JMP、JSL、CSV、XLS檔案,與其它統計分析軟體共用。更可以編輯檔案,重新存成 STDF 格式。這項獨特的編輯功能,讓您突破硬體的限制,可依每個自變相排列實驗結果。
*STDF 為 Standard Test Data Format, 它是由 Teradyne 提出的一種檔案格式, 用於半導體測試記錄測試結果。
自1986年以來,Stat/Transfer 便為世界各地數以千計的使用者提供快速、可靠而且便利的數據轉換工具。
不同統計軟體在處理數據時各有所長。當我們用不同軟體處理同一數據對象時,存在著一個數據轉換(data transfer)問題。通常,不同軟體的數據文件不是不能直接轉換,就是轉換過程比較複雜,Star/Transfer軟體可以方便地解決這一問題,其操作簡單,包含的數據類型廣泛。
Stat/Transfer 非常了解統計的數據含蓋了遺漏的數據、數值、變量的捲標和更多的細節,而且這些的數據常常需要從一個檔案的格式轉變成另一個檔案格式。
有時不只是數據的轉換;為了數據的分析、數據的清除整理和校正,還有為了數據表現形式上的修改等等,都需要做數據的轉換。如果和手動修改數據卷標相比Stat/Transfer為您節省數小時甚至數天的時間,而且更準確更具有彈性。
Stat/Transfer 提供易用的清單界面和強大的批次處理功能。不論你是將一個簡單的表格從Excel轉到SAS或是在不同的統計軟體包間移動數以兆計的監測數據,Stat/Transfer 都將為您節省時間和費用。

StatXact® 12 Presents Over 160 Tests and Procedures for Exact Inference
StatXact® 12 provides statisticians in disciplines across the social and natural sciences with the world’s most expansive toolkit for exact inference and power analysis. Offering more than 160 tests and procedures, the StatXact® suite has transformed the complex algorithms of modern statistical analysis into a validated software package with a user-friendly interface.
The Advantages of StatXact 12
StatXact offers more tests and procedures for exact inference and power analysis than any other software package on the market. Fast and accurate inferences are compiled on an easy-to-use interface, drawing on complex algorithms created by Cytel’s team of statistical experts.
Our experts are constantly developing new types of exact tests, broadening the selection of calculations available to our users. Many of these methods are only available to StatXact users, and have received acclaim for their performance from both industry and academia.
The Benefits of StatXact 12
Empower
Play a more strategic role in your organization: Perform fast and accurate hypothesis-testing that is responsive to an array of trial needs. Obtain reliable results for smaller sample sizes, allowing for timely and cost-effective trials. Redirect time, attention and critical resources to other vital aspects of study success.
Trust
StatXact has harnessed the immense power of Cytel’s nonparametric and exact inference methods to make enduring contributions to the fields across the natural and social sciences, receiving acclaim from both industry and academia for its high quality performance of complex calculations.
Share
StatXact simplifies tests that normally require complex calculation. Findings that should be difficult to compute are easy to identify and communicate.
Assess
Access StatXact’s selection of exact and Monte Carlos tests to increase the statistical power of trial results. Unnecessary risks associated with conventional (asymptotic) testing are curtailed using performance software that is fast and accurate.
The Features of StatXact 12
The Toolkit
Not only does StatXact provide more tests and procedures for exact and power analysis than any other software currently on the market, but many of these complex tests are only available to StatXact...
SUDAAN 是由 RTI International設計與研發的國際公認統計軟體,專門對於複雜的研究數據提供準確、高效的分析。SUDAAN非常適合調查和實驗研究數據的分析,因為SUDAAN計算程序正確地考慮複雜的設計功能,如相關的觀測、聚類、權重、分層。 SUDAAN 11為 SUDAAN最新版本,反映我們繼續致力於提供有用的統計工具。
SUDAAN可分析各種不同複雜調查來源:
複雜的抽樣調查數據(Data from complex sample surveys)
流行病學調查數據(Epidemiological study data)
臨床試驗數據(Clinical trial data)
實驗或觀察性研究(Experiments or observational studies)
縱向數據(Longitudinal Data)
SUDAAN考量個人學習需求所提供的設計特點,包括:
不平等的加權或不加權數據(Unequally weighted or unweighted data)
分層(Stratification)
有或沒有更換設計(With or without replacement designs)
多級和集群設計(Multistage and cluster designs)
重複測量(Repeated measures)
一般集群相關(例如,相關因病患採取多種措施、幼小動物於巢穴內,或學生在學校內)(General cluster-correlation (e.g., correlation due to multiple measures taken from patients, pups nested within litters, or students nested within schools))
多重插補分析變量(Multiply imputed analysis variables)
SUDAAN程式與估計方法
SUDAAN是由多種分析和新的預分析所組成的套裝程式。兩個預分析過程包括第一種是使用基於模型的重量校準方法( WTADJUST ),第二個是用Cox-Iannacchione Weighted Sequential Hot Dec法( HOTDECK )。所有的分析程式例如WTADJUST,皆提供了三種強大的方差估計方法:
Taylor series linearization (GEE for regression models)
Jackknife (with or without user-specified replicate weights)
Balanced repeated replication (BRR)
以上為SUDAAN替統計分析軟體所帶來的重大突破,包括可調查不同複雜來源、符合個人需求設計及提供強大的方差估計方法。
SuperSMITH 軟體是專為可靠性和統計分析而設計的,用於預測壽命、安全性、存活能力、風險、成本和保修索賠,以及通過使用Weibull、log normal、Crow-AMSAA、probit和Kaplan-Meier模型進行加速測試的證明。
SuperSMITH 軟體是唯一與由Robert Abernethy博士撰寫的行業領先的Weibull手冊兼容的軟體。
SuperSMITH包含三個獨立的程式,但它們都包含在軟體包中並且可以相互配合使用
SuperSMITH Weibull
“SSW” - makes probability scale plots showing for each data set the associated model fit line going through or near the input data measurement points. SSW solves for graphical (regression) and non-graphical (likelihood) fits to the input data. Distribution models include Weibull, normal, lognormal, Gumbel lower, and Gumbel upper. Analysis includes support for different input data types with their associated solution methods, distribution analysis for finding the best-fitting model, confidence estimation for lower and upper bounds, 3-parameter solution, and 1-parameter solution. Tools include optimum replacement interval for lowest cost, Abernethy risk for forecasting, basic mixture solution, Barringer process reliability, test planning, and accelerated testing covariate solution.
SuperSMITH Visual
“SSV” – generates standard X-Y plots, log-scale plots, Arrhenius scale plots, pie graphs, and bar charts. Analysis includes curve fitting, function viewing, and global data transforms. Tools include Crow-AMSAA (C-A) reliability growth trending, Nelson recurrent event solution, and forecasting with the C-A model. SSV also provides the auxiliary plotting engine for SSW table output visualization for forecasts and costs, confidence contour visualization, and associated SSW plots like density function, hazard function, and aggregate cumulative hazard (ACH).
SuperSMITH YBath(TM)
“SSY” – provides advanced mixture solutions for multiple underlying distributions in the same set of data. Mixture solutions include 4-parameter “Competing Risk”, 5-parameter “Competing Risk Batch”, 5-parameter “Exclusive Or”, and 7-Parameter Competing Risk mixture, which models the Bathtub curve of infant mortality, chance, and wear out. Methods include graphical (regression) and non-graphical (likelihood).
In addition to the three analysis programs, there is a common HELP program that can be called from any one of the individual programs. This file also has a "Best Practice" flow chart guide, descriptions of the icons, and a detailed summary of the models and methods available.
