Please answer part C and D
rainfall.( cov(by b) = -0.00024 gUse the model in (d) to forecast yield h. Suppose that you wanted to forecast 1997 yiel your forecast from the model in (a)? What would it be from to decline after middle S.11 When estimating wage equations, we expect that young, inexperienced workers will have relatively age, as the worker nears retirement. This life-cycle pattern of wages can be captured by introducing low wages; with additional experience their...

Let the random variable Y represent hourly wages and the random variable X represent education. Suppose we have the following regression equation in mind to estimate the return to education: (a) Can we say that this regression would capture the causal effect of education on wages? Support your answer with reasoning. (b) Using the sample equivalent of the two equations E(u)-0 and E(uX)-0 derive the regression estimators for A, and β1-Write down each mathe tnatical step, what would be the...
