The sum of the left and right tails is the p-value, 0.168, which is pretty close to what we estimated by resampling, 0.166. You can download the code I used in this section from http://thinkstats.com/hypothesis_analytic.py 7.9 PowerWhen the result of a hypothesis test is negative (...
In type 2 error computation, why do we compute the standard deviation using the value assumed under the null hypothesis even if we provide the alternative hypothesis as possible true value? If in null hypothesis u = 20, and in the alternative hypothesis u = 24, and...
To this end, the combined cointegration test and three different estimators are utilized for the period from 1980 to 2016. The main finding of the study indicates that the inverted U-shaped EKC relationship between economic complexity and environmental pollution holds for the USA. In addition to ...
This hypothesis scales a process lasting millions of years to one lasting few seconds in an analogous way a wind tunnel test scales down the large size of an aircraft to a more manageable wind tunnel model. The replication hypothesis does not require any Reynolds number corrections. The lift ...
