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

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
