Stata/BE allows data sets with as many as 2,048 variables and 2 billion observations. Stata/SE can analyse up to 2 billion observations. Stata/SE and Stata/MP can fit models with more independent variables than Stata/BE (up to 10,998). Stata/SE and Stata/BE differ only in the data set size that each can analyse. Stata/MP can analyse 10 to 20 billion observations given the current largest computers, and is ready to analyse up to 1 trillion observations once computer hardware catches up. The current version of merge uses a different syntax (requiring a 1:1, m:1, or 1:m specification) and does not allow more than one file to be merged in a single merge command. Stata/MP can also analyse more data than any other edition of Stata. NOTE: This page describes usage of an older version of the merge command (prior to Stata 11), which allowed multiple files to be merged in the same merge command.
#Stata 16 license
For example, if your machine has eight cores, you can purchase a Stata/MP license for eight cores, four cores, or two cores. You can purchase a Stata/MP license for up to the number of cores on your machine (maximum is 64). Stata/MP, Stata/SE, and Stata/BE all run on any machine, but Stata/MP runs faster. With more than two cores or processors, Stata/MP is even faster. On dual-core chips, Stata/MP runs 40% faster overall and 72% faster where it matters, on the time-consuming estimation commands. This includes the Intel i3, i5, i7, i9, Xeon, and Celeron, and AMD multi-core chips. Virtually any current computer can take advantage of the advanced multiprocessing of Stata/MP. Stata/MP is the fastest and largest edition of Stata.
