2. Find an article that uses path analysis or explanatory multiple regression on a research topic with which you are familiar and interested. If the authors’ model is not drawn in the article, see if you can draw it from their description. How do the authors justify their causal assumptions or their paths? Do you agree, or do you think some of the paths are drawn in the wrong direction? Do you think there are any obvious common causes that have not been included in the model? Can you demonstrate that there are common causes that have been neglected? If the authors included a correlation matrix with their article, see if you can reproduce their results. Draw the estimated model.
