We did some data analysis with the human development index, and this is my branch of it. You can see the other's work at:

My branch of it deals with analyzing the UN's human development index versus the social inclusion index and values from the World Values Survey representing general "human-ness".
The social inclusion index versus the HDI returned some pretty terrible results - got an R^2 value of 0.24.
For the World Values Survey, I picked the following values:
-
Mention some qualities that children should learn at home. (Binary values – mentioned = 1 or not mentioned = 2)
- V15. Imagination
- V16. Tolerance and respect for others
- V20. Unselfishness
- V22. Self-expression
-
Which of these organizations are you an active member, inactive member, or don’t belong? (Active member = 2, Inactive member = 1, Don’t belong = 0)
- V27. Art, music, or educational organization
- V32. Humanitarian or charitable organization
-
Describing some people, how much are they like you? (1 = very much like me and 6 = very much not like me)
- V70. Important to this person to think of new ideas and be creative, to do things one’s own way
- V74B. Important for this person to help the people nearby, to care for their well-being
-
How often, if at all, do you think about the meaning and purpose of life?
- V143. (1 = Often, 2 = Sometimes, 3 = Rarely, 4 = Never)
-
I see myself as someone who… (1 = Disagree strongly and 5 = Agree Strongly, and 9 = Don’t know)
- V160E. Has few artistic interests
- V160J. Has an active imagination
All of these features together yielded a R^2 = 0.695.
After doing all this, I did the "leave one out method" to see which features had the most impact. A variable name means the effect on the R^2 and adjusted R^2 had by leaving that variable out. Here are my results from that:
- All: r2 = 0.695, ar2 = 0.505
- V15: r2 = 0.694, ar2 = 0.518
- V16: r2 = 0.688, ar2 = 0.508
- V20: r2 = 0.679, ar2 = 0.494
- V22: r2 = 0.690, ar2 = 0.511
- V27_1: r2 = 0.639, ar2 = 0.432
- V32_1: r2 = 0.689, ar2 = 0.509
- V27_2: r2 = 0.667, ar2 = 0.475
- V32_2: r2 = 0.693, ar2 = 0.516
- V70_1: r2 = 0.681, ar2 = 0.497
- V70_2: r2 = 0.694, ar2 = 0.517
- V70_3: r2 = 0.659, ar2 = 0.463
- V74B_1: r2 = 0.680, ar2 = 0.497
- V74B_2: r2 = 0.643, ar2 = 0.437
- V74B_3: r2 = 0.649, ar2 = 0.446
- V143_1: r2 = 0.682, ar2 = 0.499
- V143_2: r2 = 0.692, ar2 = 0.515
- V160E_1: r2 = 0.691, ar2 = 0.513
- V160E_2: r2 = 0.695, ar2 = 0.519
- V160J_5: r2 = 0.691, ar2 = 0.513
- V160J_4: r2 = 0.695, ar2 = 0.520
In some cases, the general R^2 was kept and the adjusted R^2 went up.
