Collinearity can be a problem in regression models. When examining the effects of an exposure at different time points, constrained distributed lag models ( can alleviate some of the problems caused by collinearity. Still, some consequences of collinearity may remain and they are often unexplored. This package is a tool to assess whether unexpected results of a study could be influenced by collinearity. Essentially, the package provides a graphical comparison of the effects estimated in the real analysis with the effects estimates that would be obtained in a scenario with an alternative true pattern effect for the association of interest. The package can be also applied to regression models that do not include a distributed lag structure.
