值得信任
技术支持
我们不仅编写统计方法,我们还会进行验证。
您能从Stata estimator rest与其他估计的比较中看到Monte-Carlo模拟的一致性和覆盖率以及我们统计学家们进行的广
泛测试。每一版的Stata软件,我们都通过了各种认证,包括230万行的代码测试,并产生了430万行的结果输出。我们验
证了这430万行代码中的每一个数字和每一段文字。
Stata公司的技术团队对注册用户提供免费服务。而这远比您付的费用得到的更多。
我们有的Stata程序员和统计学家来回答您的技术问题。从棘手的数据管理方案到让您做出的图表;从解释大
量的标准错误到您进行多层模型,我们认真回答您的问题。

Advantages and disadvantages of Bayesian analysis
Bayesian analysis is a powerful analytical tool for statistical modeling, interpretation of results,
and prediction of data. It can be used when there are no standard frequentist methods available or
the existing frequentist methods fail. However, one should be aware of both the advantages and
disadvantages of Bayesian analysis before applying it to a specific problem.
The universality of the Bayesian approach is probably its main methodological advantage to the
traditional frequentist approach. Bayesian inference is based on a single rule of probability, the Bayes
rule, which is applied to all parametric models. This makes the Bayesian approach universal and
greatly facilitates its application and interpretation. The frequentist approach, however, relies on a
variety of estimation methods designed for specific statistical problems and models. Often, inferential
methods designed for one class of problems cannot be applied to another class of models.

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(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**过了SPSS,在许多方面也**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,因此计算速度较快(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**过了SAS。用Stata绘制的统计图形相当精美,很有特色。

In Stata 16, you can embed and execute Python code from within Stata. Stata's new python command allows you to easily call Python from Stata and output Python results within Stata.
You can invoke Python interactively or in do-files and ado-files so that you can leverage Python's extensive language features. You can also execute a Python file (.py) directly through Stata.
In addition, we introduced the Stata Function Interface (sfi) Python module, which provides a bi-directional connection between Stata and Python. This module lets you access Stata's current dataset, frames, macros, scalars, matrices, value labels, characteristics, global Mata matrices, and more.
All of this means that you can now use any Python package directly within Stata. For instance, you can use Matplotlib to draw 3-dimensional graphs. You can use NumPy for numerical computations. You can use Scrapy to scrape data from the web. You can access additional machine-learning techniques such as neural networks and support vector machines through TensorFlow and scikit-learn. And much more.
Finally, Stata’s Do-file Editor now includes syntax highlighting for the Python language.
While advanced users and programmers might be most likely to take advantage of Python integration, the availability of Python within Stata will excite many more users in all disciplines.
19年来,公司始终秉承、专注、专心的发展理念,厚积薄发,积累了大量的人才、技术以及行业经验,在行业内得到了大量用户的认可和高度价。
