Learn how to create a winning A/B testing hypothesis that will increase your probability of achieving success through your test.
Step three is all about articulating the impact that you predict your proposed solution will have on yourconversion problem. Remember this statement should take into accountwhatyou will be testing, andhowthat will positively impact your conversion problem. Continuing with the same example, if the co...
We study a variant of the many-help one hypothesis testing against independence problem in which the source, not necessarily Gaussian, has finite differential entropy and the observation noises under the null hypothesis are Gaussian. Under the criterion that stipulates minimization of the Type II ...
