Definition: Point and set hypothesis

Index: The Book of Statistical Proofs ▷ General Theorems ▷ Frequentist statistics ▷ Statistical hypotheses ▷ Point/exact vs. set/inexact

Definition: Let $H$ be a statistical hypothesis. Then,

• $H$ is called a point hypothesis or exact hypothesis, if it specifies an exact parameter value:

\[\label{eq:hyp-point} H: \; \theta = \theta^{*} \; ;\]

• $H$ is called a set hypothesis or inexact hypothesis, if it specifies a set of possible values with more than one element for the parameter value (e.g. a range or an interval):

\[\label{eq:hyp-non-point} H: \; \theta \in \Theta^{*} \; .\]
