1) Define p-values in the form of a conditional probability,
i.e. p-value = Prob(A|B) where you say what A and B are
2) Define likelihood (from the likelihood ratio test) in the form
of a conditional probability, i.e. likelihood = Prob(A|B) where you
say what A and B are
1) The p value is defined as the probability of the observed values given that the null hypothesis is true. So we can define p value as a conditional probability. Define two events
A = random variable represents the observed data
B=the statistical hypothesis under consideration I.e the null hypothesis
Then P(A|B) =p value .
2) The likelihood can be expressed as
P(A|B) =likelihood function
A= Theta which is the parameter of the distribution
B= random variable
P is the pdf or pmf of the random variable.
Hence it is expressed as the conditional distribution.
