Media analyses of soccer statistics and game play has accelerated in recent years. This is evident in visual displays of ball and player tracking, average player locations and distances they run. These media depictions aim to be attractive, entertaining and informative for viewers. But are such statistics predictive of goal scoring and match outcome? To answer this question we review the sixty-four matches of the 2014 World Cup and examine nine common match statistics, and others, to evaluate their predictive value for goal production and match outcome.

Nebraska Monthly Economic Indicators: September 25, 2019, Eric Thompson
Leading Economic Indicator Reports
The Leading Economic Indicator – Nebraska (LEI-N) 1 fell by 1.89% during August of 2019. The drop in the LEI-N, which is designed to predict economic activity six months into the future, follows a sharp 2.51% increase during July. Taken together, results from the two months imply modest economic growth in Nebraska at the end of 2019 and the beginning of 2020. The leading indicator fell primarily due to a an increase in initial claims for unemployment insurance and a sharp increase in the value of the U.S. dollar. A rising dollar creates challenges for Nebraska busineses which ...

An Overview And Analysis Of The Impacts Of Extreme Heat On The Aviation Industry, Brandon T. Carpenter
Pursuit - The Journal of Undergraduate Research at the University of Tennessee
Weather is a common cause of flight delays and cancellations. However, the vast majority of the time when thinking about weather and its effect on aviation, winter conditions such as snow come to mind. Heat is usually one of the last types of weather we associate with airline challenges. Recently, a bomb cyclone made headlines for the disruptions it caused with travel, especially at John F. Kennedy International Airport. Interestingly, the exact opposite of winter weather conditions can cause just as many challenges. During the summer of 2017, a number of flights at various airports such as Phoenix Sky Harbor ...

A Descriptive Study Of Variable Discretization And Cost-Sensitive Logistic Regression On Imbalanced Credit Data, Lili Zhang, Jennifer Priestley, Herman Ray, Soon Tan
Grey Literature from PhD Candidates
Training classification models on imbalanced data tends to result in bias towards the majority class. In this paper, we demonstrate how variable discretization and cost-sensitive logistic regression help mitigate this bias on an imbalanced credit scoring dataset, and further show the application of the variable discretization technique on the data from other domains, demonstrating its potential as a generic technique for classifying imbalanced data beyond credit scoring. The performance measurements include ROC curves, Area under ROC Curve (AUC), Type I Error, Type II Error, accuracy, and F1 score. The results show that proper variable discretization and cost-sensitive logistic regression with ...
