Panel analysisPanel (data) analysis is a statistical method, widely used in social science, epidemiology, and econometrics to analyze two-dimensional (typically cross sectional and longitudinal) panel data. The data are usually collected over time and over the same individuals and then a regression is run over these two dimensions. Multidimensional analysis is an econometric method in which data are collected over more than two dimensions (typically, time, individuals, and some third dimension).
Online research communityAn online research community (part of Research 2.0) is a part of an emerging and developing area in market research making use of developments in Web 2.0 technologies and online communities. They allow qualitative research to be conducted efficiently and deeply online. Both public and private online communities offer opportunities for research, but many brands are wary of sharing company information openly. Invitation-only, private online communities centred on a single brand or customer segment may be the solution.

Virtual communityA virtual community is a social network of individuals who connect through specific social media, potentially crossing geographical and political boundaries in order to pursue mutual interests or goals. Some of the most pervasive virtual communities are online communities operating under social networking services. Howard Rheingold discussed virtual communities in his book, The Virtual Community, published in 1993. The book's discussion ranges from Rheingold's adventures on The WELL, computer-mediated communication, social groups and information science.
