WitrynaLogistic regression is a simple but powerful model to predict binary outcomes. That is, whether something will happen or not. It's a type of classification model for supervised machine learning. Logistic regression is used in in almost every industry—marketing, healthcare, social sciences, and others—and is an essential part of any data ... The relative risk is different from the odds ratio, although the odds ratio asymptotically approaches the relative risk for small probabilities of outcomes. If IE is substantially smaller than IN, then IE/(IE + IN) IE/IN. Similarly, if CE is much smaller than CN, then CE/(CN + CE) CE/CN. Thus, under the rare disease assumption
