Logistic regression is a way of using math to figure out the probability of something happening. For example, we can use logistic regression to predict if a person is more likely to get a disease or not. The way it works is we feed it information about a person such as their age, gender, and lifestyle choices. With this information, logistic regression looks at how these different factors relate to each other and then gives us a percentage chance of the person getting the disease or not. Logistic regression is a useful tool for predicting and understanding the chances of something happening.
