Next, the power law nature of social interactions is described and a hypothetical example is used to explain why analyzing sub\u2010sets of data might misrepresent the relationship between variables having power law distributions. Analysis requires the use of the complete distribution. The paper proposes logarithmic transformation prior to correlation and regression analysis and shows why it works using the hypothetical example and field data retrieved from Microsoft's Netscan project.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>The hypothetical example emphasizes the importance of analyzing complete datasets harvested from social spaces. The Netscan example shows the importance of the logarithmic transformation for enabling the development of a predictive regression model based on the power law distributed data. Specifically, it shows that the number of new and returning participants are the main predictors of discussion forum activity.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>This paper offers a useful analysis tool for anyone interested in social aspects of the Internet as well as corporate intra\u2010net systems, knowledge management systems or other systems that support social interaction such as cellular phones and mobile devices. It also explains how to avoid errors by paying attention to assumptions and range restriction issues.<\/jats:p><\/jats:sec>","DOI":"10.1108\/10662240910965342","type":"journal-article","created":{"date-parts":[[2009,6,6]],"date-time":"2009-06-06T07:05:44Z","timestamp":1244271944000},"page":"266-278","source":"Crossref","is-referenced-by-count":18,"title":["Statistical inference from power law distributed web\u2010based social interactions"],"prefix":"10.1108","volume":"19","author":[{"given":"Daphne R.","family":"Raban","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eyal","family":"Rabin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"140","reference":[{"key":"key2022020820395447200_b1","doi-asserted-by":"crossref","unstructured":"Adamic, L.A.
