- How does the accuracy of prediction markets compare to public opinion polls? Prediction markets' accuracy varies widely, They both are equally accurate. Prediction markets provide less accurate forecasts Prediction markets provide more accurate forecasts.What are some of the key distinctions between a descriptive model and a prescriptive model?An automobile manufacturer observes the demand for its brand increasing as per capita income increases. Sales increases also follow low interest rates, which ease credit conditions. Buyer purchase behavior is seen to be dependent on age and gender. Other factors influencing sales appear to fluctuate almost randomly (competitor advertising, competitor dealer discounts, introductions of new competitive models).a) If sales and per capita income are positively related, classify all variables as dependent, independent, moderating, extraneous, or intervening.b) Comment on the utility of a model based on the hypothesis.
