From: Bickel, David
Subject: convolution of the double exponential distribution
Is there any R function that computes the convolution of the double
exponential distribution?
If not, is there a good way to integrate ((q+x)^n)*exp(-2x) over x from
0 to Inf for any value of q and for any positive integer n? I need to
perform the integration within a function with q and n as arguments. The
function integrate() is giving me this message:
"evaluation of function gave a result of wrong length"
