hazard function
The hazard function is a statistical tool used to describe the risk of an event occurring over time, such as failure or death. It measures the instant likelihood of that event happening at a given moment, assuming it hasn't occurred yet. Think of it as tracking the probability of something happening right now, considering the situation so far. In practical terms, it helps us understand and predict risks, such as in medicine to assess patient outcomes or in engineering to evaluate the reliability of components over time.

The hazard function, in general knowledge, refers to the rate at which an event, like failure or death, happens at a certain time, given that the event hasn't occurred yet. It helps us understand the risk associated with an event at any moment. For example, in medical studies, it can show how likely patients are to experience complications over time. It’s like measuring the likelihood that something bad will happen soon, based on how long you've already waited without it happening. Thus, it’s crucial in fields like reliability engineering and survival analysis.
