Econometrics/statistics questions (topics range from simple regression to multicollinearity. etc)

Question are attached in the document. all questions must be answered it is said that should not take more than 4 hour max but you may use more time if it helps. Question 1-8 must be answered here is a sample of one of the questions. PLease read the questions before you bid I you cannot answer them pleased do not bid. 4. Many school districts pay for new school buildings with bond issues that must be approved by majority vote in an election. Supporters of these bond issues typically argue that new buildings improve schools and thereby boost housing values. A recent economics paper used RD to test whether passage of school bonds caused housing values to rise. (a) (5 pts) What is the assignment variable (a.k.a. the running variable)? Hint: time is not the assignment variable. (b) (10 pts) Explain how to use a basic sharp RD approach to estimate the eect of school bond passage on housing values. (c) (5 pts) Provide an equation that implements the approach you described in (b). Assume you observe sale prices of individual homes. Be sure you properly subscript your variables. Requirements: NA
