Two likelihood functions are equivalent if one is a scalar multiple of the other.

The actual value of a likelihood function bears no meaning.

The integral of a likelihood function is not in general 1.

If you pick 4 or more tickets, the likelihood function has a well defined standard deviation too.

Page did not explicitly say that represents the likelihood function, but this is common usage.

The likelihood function for a survival model, in the presence of censored data, is formulated as follows.

The likelihood function from above, written in terms of the variance, is:

This is done through the calculation shown below, where is the likelihood function.

Likewise the appropriate likelihood function that should be used for a particular problem may also be in doubt.

Such features are also used as part of the likelihood function, which makes use of the observed data.
