Most Powerful Tests

A hypothesis test might make one of two types of errors. These two types of errors traditionally have been given the names "Type I Error," and "Type II Error." If the parameter…

Likelihood Ratio Tests

The likelihood ratio method of hypothesis testing is related to maximum likelihood estimators. Likelihood ratio tests are as widely used as maximum likelihood estimation. In this lesson, we provide…

Sufficiency and Unbiased

In the previous lesson on best unbiased estimators and the Cramer-Rao Lower Bound, the concept of sufficiency was not used. We will now consider how sufficiency is a powerful tool in our search for…

Data Reduction and Sufficiency

The information in a random sample is used to make inferences about an unknown parameter theta. If the sample size n is large, then the observed sample is a long list of numbers that is difficult, if…
