资源信息： 中文介绍 Stata 是一套提供其使用者数据分析、数据管理以及绘制专业图表的完整及整合性统计软件。它提供许许多多功能，包含线性混合模型、均衡重复反复及多项式普罗比模式。新版本的STATA采用最具亲和力的窗口接口，使用者自行建立程序时，软件能提供具有直接命令式的语法。Stata提供完整的使用手册，包含统计样本建立、解释、模型与语法、文献等超过一千六百页的出版品。 除了之外，Stata软件可以透过网络实时更新每天的最新功能，更可以得知世界各地的使用者对于STATA公司提出的问题与解决之道。使用者也可以透过Stata Journal获得许许多多的相关讯息以及书籍介绍等。另外一个获取庞大资源的管道就是Statalist，它是一个独立的listserver，每月交替提供使用者超过1000个讯息以及50个程序。 Stata 的统计功能 Stata 的统计功能很强，除了传统的统计分析方法外，还收集了近 20 年发展起来的新方法，如 Cox 比例风险回归，指数与 Weibull 回归，多类结果与有序结果的 logistic 回归， Poisson 回归，负二项回归及广义负二项回归，随机效应模型等。具体说， Stata 具有如下统计分析能力： 数值变量资料的一般分析：参数估计，ｔ检验，单因素和多因素的方差分析，协方差分析，交互效应模型，平衡和非平衡设计，嵌套设计，随机效应，多个均数的两两比较，缺项数据的处理，方差齐性检验，正态性检验，变量变换等。 分类资料的一般分析：参数估计，列联表分析 ( 列联系数，确切概率 ) ，流行病学表格分析等。 等级资料的一般分析：秩变换，秩和检验，秩相关等 相关与回归分析：简单相关，偏相关，典型相关，以及多达数十种的回归分析方法，如多元线性回归，逐步回归，加权回归，稳键回归，二阶段回归，百分位数 ( 中位数 ) 回归，残差分析、强影响点分析，曲线拟合，随机效应的线性回归模型等。 其他方法：质量控制，整群抽样的设计效率，诊断试验评价， kappa 等。 Stata 的作图功能 Stata 的作图模块，主要提供如下八种基本图形的制作 : 直方图 (histogram) ，条形图 (bar), 百分条图 (oneway) ，百分圆图 (pie) ，散点图 (twoway) ，散点图矩阵 (matrix) ，星形图 (star) ，分位数图。这些图形的巧妙应用，可以满足绝大多数用户的统计作图要求。在有些非绘图命令中，也提供了专门绘制某种图形的功能，如在生存分析中，提供了绘制生存曲线图，回归分析中提供了残差图等。 Stata 的矩阵运算功能 矩阵代数是多元统计分析的重要工具， Stata 提供了多元统计分析中所需的矩阵基本运算，如矩阵的加、积、逆、 Cholesky 分解、 Kronecker 内积等；还提供了一些高级运算，如特征根、特征向量、奇异值分解等；在执行完某些统计分析命令后，还提供了一些系统矩阵，如估计系数向量、估计系数的协方差矩阵等。 Stata 的程序设计功能 Stata 是一个统计分析软件，但它也具有很强的程序语言功能，这给用户提供了一个广阔的开发应用的天地，用户可以充分发挥自己的聪明才智，熟练应用各种技巧，真正做到随心所欲。事实上， Stata 的 ado 文件 ( 高级统计部分 ) 都是用 Stata 自己的语言编写的 Stata 其统计分析能力远远超过了 SPSS ，在许多方面也超过了 SAS ！由于 Stata 在分析时是将数据全部读入内存，在计算全部完成后才和磁盘交换数据，因此计算速度极快（一般来说， SAS 的运算速度要比 SPSS 至少快一个数量级，而 Stata 的某些模块和执行同样功能的 SAS 模块比，其速度又比 SAS 快将近一个数量级！） Stata 也是采用命令行方式来操作，但使用上远比 SAS 简单。其生存数据分析、纵向数据（重复测量数据）分析等模块的功能甚至超过了 SAS 。用 Stata 绘制的统计图形相当精美，很有特色。 STATA 的功能列表 数据管理 (Data management) 资料转换、分组处理、附加档案、 ODBC 、行 - 列转换、数据标记、字符串函数…等 基本统计 (Basic statistics) 直交表、相关性、 t- 检定、变异数相等性检定、比例检定、信赖区间…等 线性模式 (Linear models) 稳健 Huber/White/sandwich 变异估计 , 三阶最小平方法、类非相关回归、齐次多项式回归、 GLS 广义型线性模式 (Generalized linear models) 十连结函数、使用者 - 定义连结、 ML 及 IRLS 估计、 九变异数估计、七残差…等 二元、计数及有限应变量 (Binary, count, and limited dependent variables) 罗吉斯特、 probit 、卜松回归、 tobit 、 truncated 回归、条件罗吉斯特、多项式逻辑、巢状逻辑、负二项、 zero-inflated 模型、 Heckman 选择模式、边际影响 Panel 数据 / 交叉 - 组合时间序列 (Panel data/cross-sectional time-series) 随机及固定影响之回归、 GEE 、随机及固定 - 影响之 卜松及负二项分配、随机 - 影响、工具变量回归、 AR(1) 干扰回归 无母数方法 (Nonparametric methods) 多变量方法 (Multivariate methods) 因素分析、多变量回归、 anonical 相关系数 模型检定及事后估计量支持分析 (Model testing and post-estimation support) Wald 检定、 LR 检定、 线性及非线性组合、非线性限制检定、边际影响、修正平均数 Hausman 检定 群集分析 (Cluster analysis) 加权平均 , 质量中心及中位数联结、 kmeans 、 kmedians 、 dendrograms 、停止规则、使用者扩充 图形 (Graphics) 直线图、散布图、条状图、圆饼图、 hi-lo 图、 回归诊断图… 调查方法 (Survey methods) 抽样权重、丛集抽样、分层、线性变异数估计量、拟 - 概似最大估计量、回归、工具变量… 生存分析 (Survival analysis) Kaplan – Meier 、 Nelson – Aalen, 、 Cox 回归 ( 弱性 ) 、参数模式 ( 弱性 ) 、危险比例测试、时间共变项、 左 - 右检查、韦柏分配、指数分配… 流行病学工具 (Tools for epidemiologists) 比例标准化、病例控制、已配适病例控制、 Mantel – Haenszel, 药理学、 ROC 分析、 ICD-9-CM 时间序列 (Time series) ARIMA 、 ARCH/GARCH 、 VAR 、 Newey – West 、 correlograms 、 periodograms 、白色 - 噪音测试 , 最小整数根检定、时间序列运算、平滑化 最大概似法 (Maximum likelihood) 转换及常态检定 (Transforms and normality tests) Box – Cox 、次方转换 Shapiro – Wilk 、 Shapiro – Francia 检定 其它统计方法 (Other statistical methods) 样本数量及次方、非线性回归、逐步式回归 、统计及数学函数 包含样本范例 (Sample session) 再抽样及模拟方法 (Resampling and simulation methods) bootstrapping 、 jackknife 、蒙地卡罗模拟、排列检定 网络功能 安装新指令、网络升级、网站档案分享、 Stata 最新消息 英文介绍 Overview: Why use Stata? Stata is a complete, integrated statistical package that provides everything you need for data analysis, data management, and graphics. Stata 10 adds many new features such as multilevel mixed models, exact logistic regression, multiple correspondence analysis, a graph editor, and time-and-date variables. Find out more about these features at New in Stata 10. Fast, accurate, and easy to use With a point-and-click interface, an intuitive command syntax, and online help, Stata is easy to use, fast, and accurate (see certification results and FDA document compliance for details). All analyses can be reproduced and documented for publication and review. Broad suite of statistical capabilities Stata puts hundreds of statistical tools at your fingertips, from advanced techniques, such as survival models with frailty, dynamic panel data (DPD) regressions, generalized estimating equations (GEE), multilevel mixed models, models with sample selection, ARCH, and estimation with complex survey samples; to standard methods, such as linear and generalized linear models (GLM), regressions with count or binary outcomes, ANOVA/MANOVA, ARIMA, cluster analysis, standardization of rates, case–control analysis, and basic tabulations and summary statistics. Complete data-management facilities Stata’s data-management commands give you complete control of all types of data: you can combine and reshape datasets, manage variables, and collect statistics across groups or replicates. You can work with byte, integer, long, float, double, and string variables. Stata also has advanced tools for managing specialized data such as survival/duration data, time-series data, panel/longitudinal data, categorical data, and survey data. Publication-quality graphics Stata makes it easy to generate publication-quality, distinctly styled graphs, including regression fit graphs, distributional plots, time-series graphs, and survival plots. With the integrated Graph Editor you click to change anything about your graph or to add titles, notes, lines, arrows, and text. Responsive and extensible Stata is so programmable that developers and users add new features every day to respond to the growing demands of today’s researchers. With Stata’s Internet capabilities, new features and official updates can be installed over the Internet with a single click. Many new features and informative articles are published quarterly in the refereed Stata Journal. Another great resource is Statalist, an independent listserver where more than 2,800 Stata users exchange over 1,000 postings and 50 programs each month. Matrix programming—Mata Though you don’t need to program to use Stata, it is comforting to know that a fast and complete matrix programming language is an integral part of Stata. Mata is both an interactive environment for manipulating matrices and a full development environment that can produce compiled and optimized code. It includes special features for processing panel data, performs operations on real or complex matrices, and is fully integrated with every aspect of Stata. Learn more about Mata.
