I am a newbie in stat. I am working on the Laplace distribution for my algorithm.

  • Could tell me the first what the four moments of the Laplace distribution are?
  • Does it have infinite tail like the Cauchy distribution?
  • What is the empirical rule?

One ring to rule them all: Wikipedia: at the side you have a table holding mean, variance, skewness and kurtosis. – Nick Sabbe May 19 '11 at 15:27
Try Wikipedia? Moments. You can also use the moment-generating function. :) – cardinal May 19 '11 at 15:29
This answer may be better placed as a comment, in general. Especially since it is not self-contained. – cardinal May 19 '11 at 15:33
I'll keep that in mind. Thx. – Nick Sabbe May 19 '11 at 15:41

@Nick, I did not mean to discourage you from answering, either. Please consider submitting an answer detailing your favorite technique (or two) for deriving the results. It may be instructive for the OP and others. :) – cardinal May 19 '11 at 16:46
