Correcting and Preventing "M"-bias
MBias occurs when a covariate in an adjustment set is a collider (a variable on the colliding path between two other covariates in the adjustment set)
M-bias search is difficult between interrelationships between covariates must be considered, not just the determinants of the exposure and the outcome.
Right now, there is hard-coding to search for "M"-bias for the relationship between depression as the exposure and Alzheimer's disease as the outcome but future versions will enable search for artibrary exposures and outcomes, and produce complete reports
