Diluted Treatment Effect Estimation for Trigger Analysis in Online Controlled Experiments

Alex Deng, Victor Hu
2015 Proceedings of the Eighth ACM International Conference on Web Search and Data Mining - WSDM '15  
We derive correct dilution formulas and show for a set of widely used metrics, namely ratio metrics, correctly deriving and applying those dilution formulas are not trivial.  ...  The approach we propose in this paper is intuitive, easy to apply and general enough for all types of triggered analyses and all types of metrics.  ...  We further compared the two main trigger analysis methods: user-trigger analysis and session-trigger analysis. Data and Metrics Three A/B experiments that have different trigger rates are selected.  ...

Using web metrics to analyze digital libraries

Michael Khoo, Joe Pagano, Anne L. Washington, Mimi Recker, Bart Palmer, Robert A. Donahue
2008 Proceedings of the 8th ACM/IEEE-CS joint conference on Digital libraries - JCDL '08  
We conclude by discussing some of the limitations and possibilities in using web metrics to analyze and evaluate digital library use and impact.  ...  Using session length as our example, we recommend that this metric, which was developed to track e-commerce, be reconsidered when applied in non-ecommerce settings, such as digital libraries.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation.  ...

A Cluster Overlap Measure for Comparison of Activations in fMRI Studies [chapter]

Guillermo A. Cecchi, Rahul Garg, A. Ravishankar Rao
2009 Lecture Notes in Computer Science  
Most fMRI studies use voxel-wise statistics to carry out intrasubject as well as inter-subject analysis.  ...  In this paper we propose a novel metric called weighted cluster coverage to compare two activation maps. This metric is based on the intersection of spatially contiguous clusters of activations.  ...  The mean value of intra-session, inter-session and inter-subject overlap (using the voxel correlation metric) are plotted as a function of p.  ...

Sunandan Chakraborty, Filip Radlinski, Milad Shokouhi, Paul Baecke
2014 Proceedings of the 37th international ACM SIGIR conference on Research & development in information retrieval - SIGIR '14  
Our findings show that the outcomes of absence time agreed with the judgement of human experts performing a thorough analysis of a wide range of online and offline metrics in 14 out of these 21 cases.  ...  In a recent paper, Dupret and Lalmas introduced a new metric called absence time, which uses the time interval between successive sessions of users to measure their satisfaction with the system.  ...  The analysis of absence time and its characterization has been done by adapting the concept of survival analysis and Cox models.  ...
