Talk:Laplace distribution

From Wikipedia, the free encyclopedia

You write: "The difference between two independent identically distributed exponential random variables is governed by a Laplace distribution." How exactly? Can you give the pdf-function of the Laplace distribution in tems of lambda, where lambda is the parameter of the exponential distribution (f(t) = lambda*exp(-lambda*t)?

[edit] Redirect page needed

Can someone add a redirect from Laplace Distribution with capital letters? —The preceding unsigned comment was added by 82.211.86.2 (talk) 16:22, 11 January 2007 (UTC).

[edit] Entropy calculation

It should be better to let the \log(e) + \log(2\,b) instead of the 1 + \ln(2\,b) because \log_2(e) \ne 1.

[edit] Rounding error?

Is a Laplace distribution what one would expect for rounding error due to limited numerical precision? —Ben FrantzDale (talk) 19:01, 7 February 2008 (UTC)
