The modified Thompson Tau test is a way to find outliers in a data set. The data set must be a single variable (e.g. x1, x2,…xn). One potential outlier is tested at a time using a version of the t-test. Roughly speaking, the Tau test eliminates outliers more than two standard deviations away from the mean. Like most … See more In order to run the test, you first have to identify a possible outlier. Example question: Are any of the following points outliers? : 489, 490, 490, 491, 494, 499, 499, 500, … See more In the above example, the point with the largest absolute difference was not an outlier. If the point is an outlier, repeat the steps above for the point with the next … See more If you’re using the table, you don’t really need the formula (unless you’re calculating some specific sample size not listed). Tau is calculated from T critical values … See more WebNov 13, 2024 · Summary. Several Bayesian methods have been proposed to borrow information dynamically from historical controls in clinical trials. In this note, we identify key features of the relationship between the first method proposed, the bias–variance method, which is strongly related to the commensurate prior approach, and a more recent and …
