In all of the questions below, use finalexam.dta.

1. Estimate the effect of head's education on the probability of holding any stocks controlling for family income.
   1. Interpret the coefficient on education in terms of sign and significance.

1. Calculate the predicted probability of holding stocks for someone with 16 years of education and $100,000 in family income.
2. Graph the predicted probabilities of holding stocks on head's education if income is $100,000 and if income is $60,000 (label lines clearly).

1. Using Stata, calculate the standard deviation and the standard error of the age of "wives" (agew). In your own words, explain what these numbers mean.

1. Say you wanted to estimate the effect of log family income on log house value in the west (among non-retirees).
   1. Determine whether you have any observations with very large residuals. Provide evidence with interpretation.
   2. Assess the leverage of these large residual observations. Provide evidence with interpretation.
   3. Given the leverage finding in b, what should you do with these observations? What are your options? Weigh each option and recommend the best option.

Can you tell me the procedure how to do it with Stata?
