Records in Athletics Through Extreme-Value Theory

چکیده

We are interested in two questions on extremes relating to world records in athletics. The first question is: What is the ultimate world record in a specific athletic event (such as the 100-m race for men or the high jump for women), given today’s state of the art? Our second question is: How “good” is a current athletic world record? An answer to the second question also enables us to compare the quality of world records in different athletic events. We consider these questions for each of 28 events (14 for both men and women). We approach the two questions with the probability theory of extreme values and the corresponding statistical techniques. The statistical model is of a nonparametric nature; only some “weak regularity” of the tail of the distribution function is assumed. We derive the limiting distribution of the estimated quality of a world record. While almost all attempts to predict an ultimate world record are based on the development of world records over time, this is not our method. Instead, we use all top performances. Our estimated ultimate world record tells us what, in principle, is possible in the near future, given the present knowledge, material (shoes, suits, equipment), and drug laws.

Estimating Aging Effects in Running Events

This paper uses world running records by age to estimate a biological frontier of decline rates. Two models are compared: a linear/quadratic (LQ) model and a non-parametric model. Two estimation methods are used: 1) minimizing the squared difference between the observed records and the modeled biological frontier and 2) using extreme value theory to estimate the biological frontier that maximiz...

تحلیل موج دوام اصلاح شده، سکوی پایه ثابت، تئوری موج نو، ارزیابی

In this paper, the modification of Endurance Wave Analysis (EWA) in assessment of offshore platforms based on the new-wave theory is introduced. EWA is a new method to estimate the response of offshore structures in different sea states by use of incremental records. This study is offered practical procedures to select time duration and intensifying trend of the records. In addition, a simplifi...

Clustering of Station Observations for Extreme Value Analysis

The analysis of precipitation extremes with decadal return periods requires long data records; longer than is typically available from station observations. To address this problem, a method is proposed for clustering station records based on the similarity of their precipitation climatologies. It is demonstrated that the proposed aggregation method is superior to naive aggregation methods for ...
