Estimating Suicide Occurrence Statistics Using Google Trends
Kristoufek, Ladislav - 2017
Data on the number of people who have committed suicide tends to be reported with a substantial time lag of around two years. We examine whether online activity measured by Google searches can help us improve estimates of the number of suicide occurrences in England before official figures are...

Introducing Linear Regression : An Example Using Basketball Statistics
Arnold, Tom - 2011
The intuition behind linear regression can be difficult for students to grasp particularly without a readily accessible context. This paper uses basketball statistics to demonstrate the purpose of linear regression and to explain how to interpret its results. In particular, the student will...

Detecting Relevant Interactions in High Dimensional Data Analysis
So, Mike K. P. - 2014
In high dimensional data, relevant interactions can be difficult to identify due to the extremely large number of possible interactions among variables. Conventional methods use a screening stage to vastly reduce the dimension of the variable space before examining the interaction effect....
