In science:

Kinetic Reduced MHD (§ 5 and § 6). — On scales above the ion gyroscale, known as the “inertial range ” we demonstrate that the decoupling of the Alfvén-wave cascade and its indifference to both collisional and collisionless damping are explicit and analytically provable properties.

This sheds some light on the indifference of Alfvén waves to collisions: Alfvénic perturbations do not change the Maxwellian character of the ion distribution.

Clearly, the interval (θ0 , θ1 ) is an indifference zone, since there is no requirement imposed on probabilities of committing decision errors for θ ∈ (θ0 , θ1 ).

Since there is no requirement imposed on (θ0 , θ1 ) for the OC function, such interval (θ0 , θ1 ) is referred to as an indifference zone. A famous solution to the above problem is the Sequential Probability Ratio Test (SPRT) proposed by Abraham Wald during World War II of last century.
Sequential Tests of Statistical Hypotheses with Confidence Limits
Instead of using likelihood ratio as existing testing plans, we use confidence limits to define stopping rules and decision rules. A key idea is to compare confidence limits with the endpoint of indifference zone.
Sequential Tests of Statistical Hypotheses with Confidence Limits
We demonstrate that, for testing problems related to common distributions, the adjustment can be done by efficient computation and for such purpose it suffices to evaluate the OC function for the endpoints of the indifference zone.
