If a regression analysis was to be completed on body mass index (BMI), what could be an independent variable in that analysis? Why? If we could, what other independent variables should be included in the analysis? What statistic(s) would show the value of that regression in understanding BMI?
Alternatively, find an article that uses regression analysis to study a medical concern. In that study, what was the dependent variable and what were the independent variable(s)? Further, how would you use this study to highlight the difference between correlations and causation?

What socio-economic variables could serve as Independent variables when conducting a multiple linear Regression with the dependent variable "Happiness Index"? (I already have GDP/capita, divorce rate, unemployment rate, urbanization rate) Maybe you also can come up with an "interesting" one where there is not yet so much Research on a potential correlation with Happiness. Thanks in advance
