Lecture Notes in Computer Sciencee primary reason for uncertainty regarding causation in observational studies is the possibility of confounding. Conceptually, confounding occurs when other causes “stand in the way” of understanding a specific cause of interest. Specifically, confounding is present when characteristics other than t

Carlos Cid,Sean Murphy,Matthew Robshawionship between the predictor variables in the model and the outcome variable under study. In linear regression, each one-unit difference in a predictor variable is associated with some constant difference in the mean value of the outcome variable. In many instances, the assumption of a linear relat
