Regression Assignment | Homework For You
The information set fertility.csv contains particulars about n = 4286 women in Botswana all through 1988. This data accommodates number of children, years of education, age, and religious and monetary standing variables. Further particulars about each of the variables on this data-set is in the marketplace throughout the file fertilitydescr.pdf, which is posted along with this homework. Our protection question is to know the affect of education (what variety of years of education to undertake) on women’s fertility selections.
a. We first estimate the subsequent model using simple OLS regression: childreni = β0 + β1educi + β2agei + β3age2 i + β4urbani + β5tvi +β6catholici + β7knowmethi + β8usemethi + ui , i = 1, …, n the place our focus is on the parameter β1. Suppose at first that assumptions MLR.1 − MLR.4 for OLS are completely satisfied and estimate the model accordingly. Given the prospect that MLR.5 wouldn’t preserve, report heteroskedasticity sturdy customary errors. Report the price for the estimators of the regression coefficients, their customary errors, and their significance ranges.
b. Do you suppose that Cov(educi , ui) = zero? Make clear.
c. Most people education requirements for women in Botswana, along with these in our estimation sample, depend on supply date. These born throughout the first six months of the yr ought to keep at college until they’re roughly six months older than these born throughout the second half of the yr. first half is a dummy variable equal to at the least one if the girl was born via the primary six months of the yr, and nil in some other case. Make clear what’s required for first half to be a official instrumental variable for education. Do these assumptions seem low-cost?
d. Estimate the 1st step regression of education first half, along with the complete regressors, included throughout the half (a) OLS fertility model. Verify that the coefficient associated to f first half is vital. Use heteroskedasticity sturdy customary errors. Economics homework help
