The sign test is a statistical method to test for consistent differences between pairs of observations, such as the weight of subjects before and after treatment. Given pairs of observations (such as weight pre- and post-treatment) for each subject, the sign test determines if one member of the pair (such as pre-treatment) tends to be greater than (or less than) the other member of the pair ...
A worksheet, in the word's original meaning, is a sheet of paper on which one performs work.

In particular, three data sets are commonly used in different stages of the creation of the model: training, validation, and test sets. The model is initially fit on a training data set, [3] which is a set of examples used to fit the parameters (e.g. weights of connections between neurons in artificial neural networks) of the model.

The Grubbs test statistic is defined as. with and denoting the sample mean and standard deviation, respectively. The Grubbs test statistic is the largest absolute deviation from the sample mean in units of the sample standard deviation. This is the two-sided test, for which the hypothesis of no outliers is rejected at significance level α if.

It is commonly denoted by , and represents the chances of a true positive detection conditional on the actual existence of an effect to detect.
