**The different editions of Stata**

Stata/MP: The fastest and** **largest edition of Stata. Now in addition to its multiprocessing capabilities, Stata/MP can also analyze more data than any other flavor of Stata. Stata/MP can analyze 10 to 20 billion observations given the current largest computers, and is ready to analyze up to 281 trillion observations once computer hardware catches up.

Stata/SE: Stata for large datasets

Stata/IC: Stata for mid-sized datasets with up to 2048 variables

Most computers purchased since mid 2006 can take advantage of the advanced multiprocessing of Stata/MP. 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/SE and Stata/IC differ only in the dataset size that each can analyze.

Stata/SE and Stata/MP can fit models with more independent variables than Stata/IC (up to 65,532 with Stata/MP).

Stata/IC allows datasets with as many as 2,048 variables, and the maximum number of observations is 2.14 billion. Stata/IC can have at most 798 right-hand-side variables in a model.

All the above flavors have the same complete set of commands and features and include PDF documentation.

available? | Parallel processing? | Platforms |
---|---|---|---|---|---|---|

Stata MP | 120000 | 65,532 | 20 billion* | Yes | Yes | Win Mac Unix |

Stata SE | 32767 | 10,998 | 2.14 billion* | Yes | No | Win Mac Unix |

Stata IC | 2048 | 798 | 2.14 billion* | Yes | No | Win Mac Unix |

*The maximum number of observations is limited only by the amount of available RAM on your system

MP licenses can only be used on 64-bit computers, but they only go faster if your computer has at least the same number of processors as your license, i.e., MP2 will work more efficiently than a SE only if the computer has at least 2 processors. As you can see from the following graph, a Stata/MP is considerably faster than a Stata/SE.

**Compatible operating systems**

Stata will run on the platforms listed below. While Stata software is platform-specific, your Stata license is not; therefore, you need not specify your operating system when placing your order for a license.
