DESCRIPTION:Mega-Meta with covSTATIS: or How to Perform Multivariate Factor
  Meta-Analysis\n\nHerve Abdi - University of Texas at Dallas\n	Tuesday May 
 3\, 12-1pm\n	Register HERE\n\nAbstract: Traditional meta-analysis procedure
 s were developed to integrate and evaluate multiple studies involving a sm
 all number of variables but current scientific practices systematically in
 volve multiple variables often analyzed by multivariate factorial methods 
 such as principal component analysis and its numerous variations. These me
 thods typically generate maps that represent observations and variables as
  points or vectors in small dimensional spaces: a format that standard met
 a-analytic procedure cannot easily handle. Here\, in order to meta-analyze
  a set of multivariate studies using the same variables (and/or same obser
 vations) we propose to use a multi-table 3-way extension of metric multidi
 mensional scaling (called diSTATIS or covSTATIS) that can integrate the fa
 ctorial information produced by a set of studies. covSTATIS produces two s
 et of maps: The first set reveals the similarity between the studies and t
 he second set optimally analyzes the common and specific information of th
 e variables in the studies. This approach is illustrated with a meta-analy
 sis of a set of studies using the Survey of Autobiographical Memory (SAM)—
 a questionnaire that assesses self-reported remote mnemonic capacities com
 prising twenty-six variables organized in four subscales.\n
