How do Stata/MP, Stata/SE, and Stata/IC differ?

Stata/SE and Stata/IC differ in the size of the dataset that each one can analyze. Stata/MP is a parallel-processing-capable version of Stata/SE. Here is a general guideline:

• Stata/MP—Stata for dual core and multicore/multiprocessor computers
  
  
• Stata/SE—Stata for large datasets
  
  
• Stata/IC—the "standard" version of Stata

Stata/SE and Stata/MP can fit models with more independent variables than Stata/IC (up to 10,998) and can fit certain panel-data models with larger time-series within panel.

Stata/IC allows datasets with as many as 2,047 variables. The number of observations is limited by the amount of RAM in your computer. Stata/IC can have, at most, 798 right-hand-side variables in a model.
