Econ 620 Null hypothesis vs. alternative hypothesis Suppose that we have data y = (y1 , , yn ) and the data is generated by the true probability distribution P0 , from a family of probability distribution P indexed by . We can partition the parameter space into two subsets, 0 and A . Now, consider the following...

Null hypothesis - Wikipedia, the free encyclopedia
In statistical hypothesis testing, the null hypothesis (H 0 ) formally describes some aspect of the statistical "behaviour" of a set of data. This description is assumed to be valid unless the act...

Alternative hypothesis - Wikipedia, the free encyclopedia
In statistical hypothesis testing, the alternative hypothesis (or maintained hypothesis or research hypothesis ) and the null hypothesis are the two rival hypotheses which are compared by a stat...

While we set up our experiments to test the null hypothesis - that there is no difference between the treatment groups we then turn to the alternate (Real) hypothesis and either reject or fail to reject it. ... Null vs. Research (alternate) Hypothesis Null hypothesis...

Note that we cannot conclude the null hypothesis is true, just that it is plausible. If the question statement asks you to determine if there is a difference between the statistic and a value, then you have a two tail test, the null hypothesis, for example, would be μ = d vs the alternate hypothesis μ ≠ d;

- p-value is probability that the Null Hypothesis (H0) is true but you happen to observe some particular pattern. ... - exact distribution vs. convergence LLN says that for "big enough" N, converges to µY. Then CLT gives distribution, has a normal distribution around µ with standard deviation .
