Relative Importance Shiny Apps

Tonidandel, S. & LeBreton, J. M. (2014). RWA-Web -- A free, comprehensive, web-based, and user-friendly tool for relative weight analysis. Journal of Business and Psychology. doi: 10.1007/s10869-014-9351-z

This site enables users to calculate estimates of relative importance across a variety of situations including multiple regression, multivariate multiple regression, and logistic regression. The first link to the left will direct users to an interactive web form where, after providing some key pieces of information, the program will calculate estimates of importance using Johnson's (2000) relative weight analysis, confidence intervals around those weights, and information regarding the statistical significance of those weights.

In addition, users will be able to test whether two weights are significantly different from one another and whether weights are significantly different across groups.
