End User License Agreement
Stata 14 is a complete, integrated statistical package that provides everything you need for data analysis, data management, and graphics. Stata is not sold in modules, which means you get everything you need in one package. And, you can choose a perpetual licence, with nothing more to buy ever. Annual licences are also available.
All of the following flavours of Stata have the same complete set of commands and features and manuals included as PDF documentation within Stata.
Stata/MP: The fastest version of Stata (for dual-core and multicore/multiprocessor computers);
Stata/MP is the fastest and largest version of Stata. Most computers purchased since mid 2006 can take advantage of the advanced multiprocessing of Stata/MP. This includes the Intel Core™ 2 Duo, i3, i5, i7, and the AMD X2 dual-core chips. On dual-core chips, Stata/MP runs 40% faster overall and 72% faster where it matters - on the time-consuming estimation commands. With more than two cores or processors, Stata/MP is even faster.
Stata/MP is a version of Stata/SE that runs on multiprocessor and multicore computers. Stata/MP provides the most extensive support for multiprocessor computers and multicore computers of any statistics and data-management package.
The exciting thing about Stata/MP, and the only difference between Stata/MP and Stata/SE, is that Stata/MP runs faster—much faster. Stata/MP lets you analyse data in one-half to two-thirds of the time compared with Stata/SE on inexpensive dual-core desktops and laptops and in one-quarter to one-half the time on quad-core desktops. Stata/MP runs even faster on multiprocessor servers. Stata/MP supports up to 64 processors/cores.
In a perfect world, software would run twice as fast on two cores, four times as fast on four cores, eight times as fast on eight cores, and so on. Across all commands, Stata/MP runs 1.6 times faster on two cores, 2.1 times faster on four cores, and 2.7 times faster on eight cores. These values are median speed improvements. Half the commands run even faster.
On the other side of the distribution, a few commands do not run faster, often because they are inherently sequential, such as time-series commands.
Stata worked hard to make sure that the performance gains for commands that take longer to run would be greater. Across all estimation commands, Stata/MP runs 1.8 times faster on dual-core computers, 2.8 times faster on quad-core computers, and 4.1 times faster on computers with eight cores.
Stata/MP is 100% compatible other versions of with Stata. Analyses do not have to be reformulated or modified in any way to obtain Stata/MP’s speed improvements.
Stata/MP is available for the following operating systems:
Windows (32- and 64-bit processors);
Mac OS X (64-bit Intel processors);
Linux (32- and 64-bit processors);
Solaris (64-bit SPARC and x86-64).
To run Stata/MP, you can use a desktop computer with a dual-core or quad-core processor, or you can use a server with multiple processors. Whether a computer has separate processors or one processor with multiple cores makes no difference. More processors or cores makes Stata/MP run faster.
For more advice on purchasing/upgrading to Stata/MP or for hardware queries, please contact our sales team.
Stata SE performs in the same way as Stata/MP, allowing for the same number of variables and observations and the only difference is that it is not designed for parallel processing.
In addition, Stata/SE, Stata/IC and Small Stata differ only in the dataset size that each can analyse Stata/SE and Stata/MP can fit models with more independent variables than Stata/IC (up to 10,998).
Stata/IC allows datasets with as many as 2,047 variables. The maximum number of observations is 2.14 billion. Stata/IC can have at most 798 right-hand-side variables in a model.
Small Stata is limited to analysing datasets with a maximum of 99 variables and 1,200 observations. Small Stata can have at most 99 right-hand-side variables in a model.

Whether you're a student or a seasoned research professional, a range of Stata packages are available and designed to suit all needs.
All of the following flavours of Stata have the same, complete set of commands and features and include PDF documentation:
Stata/MP: The fastest version of Stata (for dual- and multicore/multiprocessor computers)
Stata/SE: Stata for large datasets
Stata/IC: Stata for moderate-sized datasets
Small Stata: A version of Stata that handles small datasets (for educational purchases only)
What Stata is right for me?
The summary above shows the Stata packages available.
Stata/MP is the fastest and largest version of Stata. Most computers purchased after mid-2006 can take advantage of the advanced multiprocessing capabilities of Stata/MP.
Stata/MP, Stata/SE, and Stata/IC all run on any machine, but Stata/MP runs faster. You can buy a Stata/MP license for up to the number of cores on your machine (the most is 64). For example, if your machine has eight cores, you can buy a Stata/MP license for either eight cores (Stata/MP8), four cores (Stata/MP4), or two cores (Stata/MP2).
Stata/MP can also analyse more data than any other flavour of Stata. Stata/MP can analyse 10 to 20 billion observations given the current largest computers, and is ready to analyse up to 281 trillion observations once computer hardware catches up.
Stata/SE, Stata/IC, and Small Stata differ only in the dataset size that each can analyse. Stata/SE and Stata/MP can fit models with more independent variables than Stata/IC (up to 10,998). Stata/SE can analyse up to 2 billion observations.
Stata/IC allows datasets with as many as 2,047 variables and 2 billion observations. Stata/IC can have at most 798 right-hand-side variables in a model.
Small Stata is limited to analysing datasets with a maximum of 99* variables and 1,200* observations. Small Stata can have at most 98 right-hand-side variables in a model.
Note: The number of variables and observations allowed by Small Stata includes the additional variables or observations generated during statistical computations.

Our 2017 Econometrics Summer School, Cambridge will take place on 15-22 July 2017 and will be held at Clare College, University of Cambridge. The School comprises 3x 2.5-day econometrics short courses delivered by leading Econometricians from the University of Cambridge: Prof. Andrew Harvey, Prof. Sean Holly and Dr. Melvyn Weeks.
The three courses comprising the School are - Time Series Analysis & Modelling / Macroeconomic Modelling & Forecasting / Microeconometrics
This 2-day course provides a review of and a practical guide to several major econometric methodologies frequently used to model the stylised facts of the financial time series via ARMA models, univariate and multivariate GARCH models, risk management analysis and contagion. Demonstration of the alternative techniques will be illustrated using Stata. Practical sessions within the course involve interest rate data, asset prices and forex time series.
The course is delivered by Prof. Giovanni Urga, an author of Financial Econometrics using Stata - Boffelli, S and Urga, G (2016), Stata Press: TX. The course is based on the book and all attendees will receive a complimentary copy.
