Why might two unrelated economic time-series exhibit a strong correlation? (Note: a strong correlation even though the variables represent unrelated phenomena). Why must we weight the residuals when analyzing proportions data (with the logic model)?

Description
Why might two unrelated economic time-series exhibit a strong correlation? (Note: a strong correlation even though the variables represent unrelated phenomena). Why must we weight the residuals when analyzing proportions data (with the logic model)? What is the relationship between Maximum Likelihood Estimator's second-order conditions and the standard errors of the coefficient estimates? Describe the different types of probability models (Probit, Logit, Multinomial Logit, Tobit). Under what conditions are they used?
