Regrex: a java-based package for teaching and active learning in regression
MetadataShow full item record
REGREX is a software system designed to improve teaching and learning some concepts in regression. Even though there is a lot of commercial statistical software we have chosen to develop this computerized package, in order to focus on the pedagogical issues. In order to do this we have developed REGRESS (Marinoiu and Dobre, 2001), presented at CBLIS’2001, in Brno, Cehia. REGREX is an improved version of REGRESS. Obviously, in REGREX we enlarge the base of regression topics. However the main gain with this new version is the possibility to offer to our students the support for active and discovery-based learning. Simulated experiments using Java applets are the main means for that.
