Advantages
The commonly used variant of Mersenne Twister, MT19937, which produces a sequence of 32-bit integers, has the following desirable properties:
- It has a very long period of 219937 − 1. While a long period is not a guarantee of quality in a random number generator, short periods (such as the 232 common in many software packages) can be problematic.
- It is k-distributed to 32-bit accuracy for every 1 ≤ k ≤ 623 (see definition below).
- It passes numerous tests for statistical randomness, including the Diehard tests. It passes most, but not all, of the even more stringent TestU01 Crush randomness tests.

Famous quotes containing the word advantages:
“For, the advantages which fashion values, are plants which thrive in very confined localities, in a few streets, namely. Out of this precinct, they go for nothing; are of no use in the farm, in the forest, in the market, in war, in the nuptial society, in the literary or scientific circle, at sea, in friendship, in the heaven of thought or virtue.”
—Ralph Waldo Emerson (1803–1882)
“The advantages found in history seem to be of three kinds, as it amuses the fancy, as it improves the understanding, and as it strengthens virtue.”
—David Hume (1711–1776)
“If the minds of women were enlightened and improved, the domestic circle would be more frequently refreshed by intelligent conversation, a means of edification now deplorably neglected, for want of that cultivation which these intellectual advantages would confer.”
—Sarah M. Grimke (1792–1873)
