Problem
Investigate the determinants of family size by regressing SIBLINGS on SM and SF using your EAEF data set. SM and SF are likely to be highly correlated (find the correlation in your data set) and the regression may be subject to multicollinearity. Introduce the restriction that the theoretical coefficients of SM and SF are equal and run the regression a second time replacing SM and SF by their sum, SP. Evaluate the regression results.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
