Stata/SE, Stata/IC和Small Stata主要的区别在于每个版本能够分析的数据集大小。Stata/MP是一个拥有并行处理能力的Stata/SE。
Stata/MP:运行最快和处理数据集最大的Stata版本。它通过并发运行多处理器或内核来加快运算速度。Stata/SE和Stata/MP允许数据集最多可达32,767个变量。观测值的数量仅受您计算机内存大小的限制。Stata/SE和Stata/MP在计算机内存大小足够的情况下允许最大11,000 x 11,000维矩阵。相关的是Stata/SE和Stata/MP能够拟合带有更多的自变量(最多10,998)的模型。
StataCorp have released a new major release of Stata, it’s a complete, integrated statistical software package that provides everything you need for data analysis, data management, and graphics.
Stata/MP lets you analyze data in one-half to two-thirds the time compared with Stata/SE on inexpensive dual-core laptops, and in one-quarter to one-half the time on quad-core desktops and laptops. Stata/MP runs even faster on multiprocessor servers. Stata/MP supports up to 64 cores/processors.
Speed is often most crucial when performing computationally intense estimation procedures. A few of Stata’s estimation procedures, including linear regression, are nearly perfectly parallelized, meaning they run twice as fast on two cores, four times as fast on four cores, eight-times as fast on eight cores, and so on. Some estimation commands can be parallelized more than others. 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.
Speed can also be important when managing large datasets. Adding new variables is nearly 100 percent parallelized and sorting is 80 percent parallelized.
Some procedures are not parallelized and some are inherently sequential, meaning they run the same speed in Stata/MP.
