Other methods
The most widely used form of hypothesis testing is the classical method introduced by Neyman and Pearson,
which utilise the likelihood function for decision between hypotheses. For comparison with the MML test
criteria, the commonly used classical tests are presented here.
In all cases, the critical value is found by finding that value of the statistic that yields the required
value of α when the probability function is evaluated.

In all cases, the critical value is found by finding that value of the statistic that yields the required
value of α when the probability function is evaluated. Hence rejection occurs when:
