In regression, we call Y the response or dependent variable, which is modeled in terms of one or more "independent" variables. The independent variables are further classified as explanatory/causal variables or as predictor variables. Discuss and elaborate on whether or not time can be a legitimate explanatory/causal variable, whether time can be a legitimate predictor variable whether a predictor variable must also be a causal/explanatory variable. Provide examples to support your arguments.
