Stata (,^[ii] STAY-ta, alternatively , occasionally stylized as STATA^{[three] [4]}) is a general-purpose statistical software package developed by StataCorp for data manipulation, visualization, statistics, and automatic reporting. It is used past researchers in many fields, including biomedicine, epidemiology, sociology and science.^[5]

Stata was initially developed by Calculating Resource Centre in California and the first version was released in 1985.^[6] In 1993, the company moved to Higher Station, TX and was renamed Stata Corporation, at present known as StataCorp.^[1] A major release in 2003 included a new graphics system and dialog boxes for all commands.^[6] Since then, a new version has been released in one case every 2 years.^[7] The current version is Stata 17, released in Apr 2021.^[8]

Technical overview and terminology [edit]

User interface [edit]

From its creation, Stata has always employed an integrated command-line interface. Starting with version 8.0, Stata has included a graphical user interface based on Qt framework which uses menus and dialog boxes to give access to many built-in commands. The dataset can be viewed or edited in spreadsheet format. From version 11 on, other commands tin be executed while the data browser or editor is opened.

Data structure and storage [edit]

Until the release of version sixteen,^[9] Stata could but open up a single dataset at any ane time. Stata allows for flexibility with assigning information types to data. Its compress command automatically reassigns data to data types that have up less retentivity without loss of information. Stata utilizes integer storage types which occupy simply one or two bytes rather than iv, and unmarried-precision (4 bytes) rather than double-precision (8 bytes) is the default for floating-point numbers.

Stata's information format is e'er tabular in format. Stata refers to the columns of tabular information every bit variables.

Data format compatibility [edit]

Stata can import information in a variety of formats. This includes ASCII information formats (such as CSV or databank formats) and spreadsheet formats (including various Excel formats).

Stata's proprietary file formats have changed over time, although not every Stata release includes a new dataset format. Every version of Stata tin can read all older dataset formats, and tin write both the electric current and nearly recent previous dataset format, using the saveold command.^[x] Thus, the electric current Stata release can always open datasets that were created with older versions, but older versions cannot read newer format datasets.

Stata can read and write SAS XPORT format datasets natively, using the fdause and fdasave commands.

Some other econometric applications, including gretl, tin can directly import Stata file formats.

History [edit]

Origins [edit]

The evolution of Stata began in 1984, initially by William (Nib) Gould and later by Sean Becketti. The software was originally intended to compete with statistical programs for personal computers such as SYSTAT and MicroTSP.^[6] Stata was written, then equally at present, in the C programming linguistic communication, initially for PCs running the DOS operating system. The get-go version was released in 1985 with 44 commands.^[6]

Commands in Stata 1.0 and Stata 1.1

append	dir	infile	plot	spool
beep	do	input	query	summarize
by	drop	characterization	backslide	tabulate
capture	erase	list	rename	test
ostend	exit	macro	supersede	type
convert	expand	merge	run	use
correlate	format	change	save
count	generate	more	set
depict	help	outfile	sort

Development [edit]

There have been 17 major releases of Stata betwixt 1985 and 2021, and boosted code and documentation updates between major releases.^[7] In its early years, extra sets of Stata programs were sometimes sold as "kits" or distributed equally Support Disks. With the release of Stata 6 in 1999, updates began to be delivered to users via the spider web.^[6] The initial release of Stata was for the DOS operating organization. Since then, versions of Stata have been released for systems running Unix variants similar Linux distributions, Windows, and MacOS.^[half-dozen] All Stata files are platform-contained.

Hundreds of commands accept been added to Stata in its 36-year history.^{[xi] [12]} Certain developments have proved to exist particularly important and continue to shape the user experience today, including extensibility, platform independence, and the active user community.^[6]

Extensibility [edit]

The plan command was implemented in Stata ane.two, giving users the power to add their own commands.^{[6] [xiii]} ado-files followed in Stata 2.1, allowing a user-written programme to be automatically loaded into memory. Many user-written ado-files are submitted to the [ Statistical Software Components Archive] hosted past Boston College. StataCorp added an ssc control to let community-contributed programs to be added directly inside Stata.^[fourteen] More than recent editions of Stata let users to telephone call Python and R scripts using commands, besides as allowing Python IDEs like Jupyter Notebooks to import Stata commands.^{[15] [16]}

[edit]

A number of important developments were initiated by Stata's active user customs.^[six] The Stata Technical Bulletin, which ofttimes contains user-created commands, was introduced in 1991 and issued 6 times a year. It was relaunched in 2001 equally the peer-reviewed Stata Periodical, a quarterly publication containing descriptions of community-contributed commands and tips for the effective use of Stata. In 1994, a listserv began as a hub for users to collaboratively solve coding and technical issues; in 2014, information technology was converted into a web forum. In 1995, Statacorp began organizing user and developer conferences that encounter annually. Only the almanac Stata Conference held in the Us is hosted past StataCorp. Other user group meetings are held annually in the United States (the Stata Briefing), the Uk, Federal republic of germany, and Italy, and less oftentimes in several other countries. Local Stata distributors host User Grouping meetings in their ain countries.

Software products [edit]

In that location are four builds of Stata: Stata/MP, Stata/SE, Stata/Be, and Numerics by Stata.^[17] Whereas Stata/MP allows for built-in parallel processing of certain commands, Stata/SE and Stata/BE are bottlenecked and limit usage to only one single cadre.^[18] Stata/MP runs certain commands about two.iv times faster, roughly 60% of theoretical maximum efficiency, when running parallel processes on four CPU cores compared to SE or BE versions.^[18] Numerics past Stata allows for web integration of Stata commands.

SE and Be versions differ in the amount of memory datasets may employ. Though Stata/MP can shop 10 to 20 billion observations and upwardly to 120,000 variables, Stata/SE and Stata/BE store up to ii.xiv billion observations and handle 32,767 variables and 2,048 variables respectively. The maximum number of independent variables in a model is 65,532 variables in Stata/MP, 10,998 variables in Stata/SE, and 798 variables in Stata/BE.^[17]

The pricing and licensing of Stata depends on its intended use: business, government/nonprofit, education, or pupil. Unmarried user licenses are either renewable annually or perpetual. Other license types include a unmarried license for use by concurrent users, a site license, book single user for majority pricing, or a student lab.^[19]

Instance lawmaking [edit]

The following set of commands revolve around elementary data management.^[20]

                        sysuse            auto            // Open the included automobile dataset            browse            // Browse the dataset (opens the Data Editor window)            describe            // Describes the dataset and associated variables            summarize            // Summary information about numerical variables            codebook            make foreign            // Summary information about the make (cord) and foreign (numeric) variables            browse if            missing(rep78)            // Browse only observations with missing data for variable rep78            list            make              if            missing(rep78)            // Listing makes of the cars with missing information for variable rep78          

The next set up of commands move onto descriptive statistics.

                        summarize            toll, detail            // Detailed summary statistics for variable cost            tabulate            foreign            // 1-manner frequency table for variable strange            tabulate            rep78 strange, row            // 2-style frequency table for variables rep78 and foreign            summarize            mpg              if            foreign            ==            one            // Summary information about mpg if the motorcar is foreign (the "==" sign tests for equality)            by            foreign,              sort:              summarize            mpg            // As above, simply using the "by" prefix.            tabulate            strange,              summarize(mpg)            // As above, simply using the tabulate command.          

A simple hypothesis test:

                        ttest            mpg,              by(strange)            // T-exam for difference in means for domestic vs. foreign cars          

Graphing information:

                        twoway            (scatter mpg weight)            // Scatter plot showing relationship between mpg and weight            twoway            (scatter mpg weight),              by(foreign,              full)            // 3 graphs for domestic, foreign, and all cars          

Linear regression:

                        generate            wtsq = weight^            2            // Create a new variable for weight squared            regress            mpg weight wtsq foreign,              vce(robust)            // Linear regression of mpg on weight, wtsq, and foreign            predict            mpghat            // Create a new variable contained the predicted values of mpg            twoway            (scatter mpg weight) (line mpghat weight,              sort),              by(foreign)            // Graph data and fitted line
