Does anyone know what bullseye distribution is?
It should be a special case of Weibull distribution, but I haven't found any useful information after googled it.
Just for information, I heard this term from a german.
So it could be some uncommon translation from german to english.
And moreover, it represents a result due to a combination of independent impacts.
Thanks a lot. I would say this is a proper math question though no formulae are involved.
UPDATE: Thanks Ross Millikan for the answer!
I have some following questions.
Does Rayleigh distribtuion only represent a 2D Gaussian distribution?
For completeness, this statement can be made as following:
$X \sim N(\mu, \sigma)$ and $Y \sim N(\mu, \sigma)$
then $\sqrt{X^{2}+Y^{2}} \sim Rayleigh(\sigma)$
So, is there a distribution which can be explicitly written for multidimensional Gaussian distribtuion,lets say N-dim?
