Re: (statistics)how to make date more like Laplacian distribution?

Hello Walala,

How big is your sample size? If you grab only100 samples, you wouldn't
expect it to exactly fit the generating distribution. Can you grab 1,000,000
samples? If still it doesn't fit, then suspect your generating dist. is
different from a Laplacian. You can look into bootstrapping methods to get
an estimate of the dist.
