New reporting features in Stata 16:
• The dyndoc and markdown commands now create Word documents in addition to the HTML documents they previously created. Now, you can easily incorporate full Stata output and graphs with Markdown-formatted text to create customized Word documents.
• The Do-file Editor now provides syntax highlighting for Markdown language elements.
• The putdocx command now lets you include headers, footers, and page numbers. It also makes it easier to write large blocks of text.
• The html2docx command converts HTML documents, including CSS, to Word documents.
• The docx2pdf command converts Word documents to PDFs.

What is Bayesian analysis?
Bayesian analysis is a statistical analysis that answers research questions about unknown parameters
of statistical models by using probability statements. Bayesian analysis rests on the assumption that
all model parameters are random quantities and thus are subjects to prior knowledge. This assumption
is in sharp contrast with the more traditional, also called frequentist, statistical inference where all
parameters are considered unknown but fixed quantities. Bayesian analysis follows a simple rule
of probability, the Bayes rule, which provides a formalism for combining prior information with
evidence from the data at hand. The Bayes rule is used to form the so called posterior distribution of
model parameters. The posterior distribution results from updating the prior knowledge about model
parameters with evidence from the observed data. Bayesian analysis uses the posterior distribution to
form various summaries for the model parameters including point estimates such as posterior means,
medians, percentiles, and interval estimates such as credible intervals. Moreover, all statistical tests
about model parameters can be expressed as probability statements based on the estimated posterior
distribution.

Sample-size analysis for confidence intervals in Stata 16
The new ciwidth command performs Precision and Sample Size (PrSS) analysis, which is sample-size analysis for confidence intervals (CIs). This method is used when you are planning a study and you want to optimally allocate resources when CIs are to be used for inference. Said differently, you use this method when you want to estimate the sample size required to achieve the desired precision of a CI in a planned study.
ciwidth produces sample sizes, precision, and more that are required for the
• CI for one mean
• CI for one variance
• CI for two independent means
• CI for two paired means
The control panel interface lets you select the analysis type and input assumptions to obtain desired results.
ciwidth allows results to be displayed in customizable tables and graphs.
ciwidth also provides facilities for you to add your own methods.

Stata是一款完整的、集成的统计软件包,提供您需要的一切数据分析、数据管理和图形。
快速,简单并易于使用
点击式的界面和强大,直观的命令语言让Stata使用起来快速,并易于使用。
所有的分析结果都可以被复制和存档,并用来出版和审查。不管您什么时候写的内容,版本控制系统确保统计程序可继续生成同样的结果。
新版本的STATA采用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**过一万余页的出版品。
除此之外,Stata软件可以透过网络实时更新每天的新功能,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,它是一个立的listserver,每月交替提供使用者**过1000个讯息以及50个程序。
使用Mata进行矩阵编程
Mata是一个成熟的编程语言,可编译您所输入的任何字节,并进行优化和准确执行。
尽管您不需要使用Stata进行编程,但是它作为一个快速完成矩阵的编程语言,是Stata功能中不可或缺的一部分。Mata既是一个操作矩阵的互动环境,也是一个完整开发环境,可以生产编译和优化代码。它还包含了一些功能来处理面板数据、执行真实或复制的矩阵运算,提供完整的支持面向对象的编程,并完全兼容Stata。
跨平台兼容
Stata可在Windows,Mac和Linux/Unix电脑上运行,但是license不需要区分电脑系统。也就是说,如果您有一台Mac系统的电脑和一台Windows系统的电脑,您不需要2个license来运行Stata。您可以安装在任意支持的系统中安装Stata软件。Stata数据集、程序以及其他的数据*翻译就可以跨平台的共享。您还可以从其他的统计软件、电子报表和数据库中轻松而快速的导入数据。
