Statistical Inference

Statistical inference is a fundamental component of extreme value theory, and the work of the Gumbel brothers was instrumental in its development. Statistical inference allows us to make inferences about the population of extreme events from a limited sample of data. This is important because extreme events are rare, and it is often difficult to collect a large enough sample of data to make accurate predictions about their occurrence.

The Gumbel brothers developed a number of statistical methods for making inferences about extreme events from limited data. These methods are based on the assumption that extreme events follow a specific probability distribution, such as the Gumbel distribution. This assumption allows us to use statistical techniques to estimate the parameters of the distribution, and to make predictions about the occurrence of extreme events.

Statistical inference is used in a wide range of applications, including environmental modeling, financial risk assessment, and engineering design. For example, statistical inference is used to estimate the probability of occurrence of floods, earthquakes, and financial crises. This information is used to design systems that can withstand these events, and to make decisions about how to mitigate their impact.

Here is a table summarizing the key insights regarding the connection between statistical inference and the Gumbel brothers:
