WebNov 19, 2011 · Abstract. The true level a n (F) of a test at nominal level a and sample size n is said to be pointwise robust if a n n =sup ℱ a n (F). The test is said to be uniformly robust over ℱ if a n t-test and confidence intervals for the binomial proportion p, are treated in detail. It is shown that the t-test is not uniformly robust if ℱ ... WebDec 17, 2014 · t.test (data, time, paired = TRUE) Paired t-test data: data and time t = …
