I was under the impression that the likelihood function was simply the probability density function but viewing the parameter theta as the variable instead of the observations x. Ie(adsbygoogle = window.adsbygoogle || []).push({});

p(x|theta) = L(theta|x)

However, the likelihood function is no longer a probability function

See Example 1 here:

Can anyone explain this a little bit?

Thanks,

Dave
