Dale replied to the thread Graduate Hypothesis testing: Defining H0, HA hypotheses so that ( H_A)_A' makes sense.With frequentist statistics you cannot speak of the probability of hypotheses, so you can only calculate ##P(D|H_0)##. With Bayesian... -
Dale replied to the thread Graduate Hypothesis testing: Defining H0, HA hypotheses so that ( H_A)_A' makes sense.Ah, I see your question and my confusion. Let’s say that you are doing a placebo controlled randomized test for a medicine to reduce... -

Like.
Well, at least in the Frequentist set up , we don't get to actually accept, just conclude we don't have enough evidence to reject or not... -
Dale replied to the thread High School Does acceleration affect impact energy vs constant velocity?.Or if the distance moved at the point of application of the external force is small, then the additional energy would be negligible. -

Like.
It depends whether the force producing the acceleration is maintained throughout the collision. For example, if you have a vertical... -
Dale replied to the thread Undergrad Synchronizing clocks in an inertial frame if light is anisotropic.That is a matter of definitions. Some authors make that requirement, other authors do not. -
Dale replied to the thread High School Thought Experiment on Charge Carriers and Electrical Conduction.What you describe is just an odd plasma. It is odd because it is completely ionized and because the two charge carriers are... -
Dale replied to the thread Graduate Hypothesis testing: Defining H0, HA hypotheses so that ( H_A)_A' makes sense.Why wouldn’t they be exhaustive? -
Dale replied to the thread Undergrad Revisiting the Light Clock.@DmitryS the recommendation to use the Lorentz transform has now come from four or five different people. You should probably take it...
