Random numbers in STATA. STATA uses a pseudo-random number function uniform() to generate random numbers. If you type in: .generate randnum = uniform 

答：Stata的说明里说 “Without loss of pseudorandomness, the seed may be set to small numbers; e.g., set seed = 2.”，即可以设置很小，（不丢失伪随机性的前提下）没问题的。

Distinguish between [], which are to be typed, and set seed 是用来做什么的？,想请教大家一个问题：在生成随机数之前，一般要set seed , 请问这个是用来做什么的？ 并且 set seed 后面跟的数字有什么用，比如 set seed 100 和 set seed 1000的区别是什么？ I gather from the Stata manual on the RNG seed that the value for the seed is 123456789 every time Stata is launched. My questions are Was it always this way or was the default seed different in o Title stata.com set seed — Specify random-number seed and state DescriptionSyntaxRemarks and examplesReference Also see Description set seed # specifies the initial value of the random-number seed used by therandom-number functions, such as runiform() and rnormal().

However, I'm wondering, why when we set the set.s Stata then combines these estimates to obtain one set of inferential statistics. mi estimate: regress read write female math progcat1 progcat2 This step combines the parameter estimates into a single set of statistics that appropriately reflect the uncertainty associated with the imputed values.
