summarize shows that the new variable has a mean of approximately zero; 10��9 is the precision of
a float and is close enough to zero for all practical purposes. If we wanted, we could have typed
egen double stdage = std(age), making stdage a double-precision variable, and the mean would
have been 10��16. In any case, summarize also shows that the standard deviation is 1. correlate
shows that the new variable and the original variable are perfectly correlated.

Stata 是一套提供其使用者数据分析、数据管理以及绘制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。用Stata绘制的统计图形相当精美。

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.
