Homework 2 I started analyzing the data and the various independent variables. I checked for the missing values (“Data Summary” Tab in excel) and built four different models. First I ran my regression with all the variables and then I started eliminating insignificant independent variables with several missing data points in 3 different regressions but my models got worse. So I picked my first model to be my final model. Overweight and Obese and the largest number of missing columns (Also see “Several Models-Female” and “Model Summary-Male” tabs in excel). But it is difficult to ascertain these values and therefore it has been ignored. The “Yes” response for these variables is substantially lower than the no response. It appears as if most people are reluctant to give a yes answer to the controversial questions asked. People are more likely to reply in a yes to easy questions about eating healthy (juice/vegetables), sports and physical activity, watching TV and whether they are sexually active. Question B.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
