Accuracy is also used as a statistical measure of how well a binary classification test correctly identifies or excludes a condition. That is, the accuracy is the proportion of correct predictions (both true positives and true negatives) among the total number of cases examined. As such, it compares estimates of pre- and post-test probability. To make the context clear by the semantics, it is often referred to as the "Rand accuracy" or "Rand index". It is a parameter of the test. The f… Web4 mrt. 2024 · In this tutorial, we’ll go over the basic ideas of floating-point representation and learn the limits of floating-point accuracy, when doing practical numerical computing. 2.
