Stata ( / ˈ s t eɪ t ə / , STAY -ta , alternatively / ˈ s t æ t ə / , occasionally stylized as STATA) is a general-purpose statistical software package developed by StataCorp for data manipulation, visualization, statistics, and automated reporting. It is used by researchers in many fields, including biomedicine , economics , epidemiology , and sociology .
44-465: Stata was initially developed by Computing Resource Center in California and the first version was released in 1985. In 1993, the company moved to College Station, Texas and was renamed Stata Corporation, now known as StataCorp. A major release in 2003 included a new graphics system and dialog boxes for all commands. Since then, a new version has been released once every two years. The current version
88-461: A bottleneck occurs when the capacity of an application or a computer system is limited by a single component, like the neck of a bottle slowing down the overall water flow. The bottleneck has the lowest throughput of all parts of the transaction path. System designers try to avoid bottlenecks through direct effort towards locating and tuning existing bottlenecks in a software application. Some examples of engineering bottlenecks that appear include
132-462: A 217-39 vote, with John H. Binney as the first mayor. Within a year, the city established a zoning commission, and by 1940, the population had reached 2,184. The city grew under the leadership of Ernest Langford, called by some the "Father of College Station", who began a 26-year stretch as mayor in 1942. Early in his first term, the city adopted a council-manager system of city government. Population growth accelerated following World War II as
176-544: A construction camp on the Houston and Texas Central Railroad. The town's name has been attributed to a well at the construction camp, a foreman named E.W. Wellborn, or a landowner named W.W. Willburn. Also in 1867, a post office opened in the community under the name Wellborn Station. In 1870, the name was shortened to Wellborn. On April 14, 2011, the City Council of College Station voted 5–2 to annex Wellborn, thus making
220-412: A land-grant school. In 1876, as the nation celebrated its centennial , the school (renamed Texas A&M University in 1963) opened its doors as the first public institution of higher education in the state of Texas. College Station's population grew slowly, reaching 350 in 1884 and 391 at the turn of the century. However, during this time, transportation improvements took place in the town. In 1900,
264-402: A new dataset format. Every version of Stata can read all older dataset formats, and can write both the current and most recent previous dataset format, using the saveold command. Thus, the 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

396-471: Is Stata 18, released in April 2023. From its creation, Stata has always employed an integrated command-line interface. Starting with version 8.0, Stata has included a graphical user interface 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 can be executed while the data browser or editor

792-524: The C programming language, initially for PCs running the DOS operating system. The first version was released in 1985 with 44 commands. There have been 18 major releases of Stata between 1985 and 2024, and additional code and documentation updates between major releases. In its early years, extra sets of Stata programs were sometimes sold as "kits" or distributed as Support Disks. With the release of Stata 6 in 1999, update s began to be delivered to users via
836-631: The I&GN Railroad was extended to College Station (the Missouri Pacific Railroad Company abandoned the line in 1965), and 10 years later, electric interurban service was established between Texas A&M and the neighboring town of Bryan. A city bus system replaced the interurban in the 1920s. In 1930, the community to the north of College Station, known as North Oakwood, was incorporated as part of Bryan. College Station did not incorporate until October 19, 1938, after

The program command was implemented in Stata 1.2, giving users the ability to add their own commands. ado-files followed in Stata 2.1, allowing a user-written program to be automatically loaded into memory. Many user-written ado-files are submitted to the Statistical Software Components Archive hosted by Boston College. StataCorp added an ssc command to allow community-contributed programs to be added directly within Stata. More recent editions of Stata allow users to call Python scripts using commands, as well as allowing Python IDEs like Jupyter Notebooks to import Stata commands. Although Stata does not support R natively, there are user-written extensions to use R scripts in Stata. A number of important developments were initiated by Stata's active user community. The Stata Technical Bulletin , which often contains user-created commands,

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.

Other user group meetings are held annually in the United States (the Stata Conference), the UK, Germany, and Italy, and less frequently in several other countries. Local Stata distributors host User Group meetings in their own countries. There are four builds of Stata: Stata/MP, Stata/SE, Stata/BE, and Numerics by Stata. 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 core. Stata/MP runs certain commands about 2.4 times faster, roughly 60% of theoretical maximum efficiency, when running parallel processes on four CPU cores compared to SE or BE versions. Numerics by Stata allows for web integration of Stata commands. SE and BE versions differ in

1760-411: The theory reveals that improving the efficiency of a particular process stage rather than the constraint can generate even more delay and decrease overall processing capabilities of a software. It is impossible to remove bottlenecks completely since there is always a component that limits the overall performance, so the usual goal is to improve the bottleneck component so that the whole system can achieve
