Appendix 1: Happiness measures used
CodeFull Text
O-SLu-u-sq-v-5-aSelfreport on single question:

On the whole, are you…?
5 fully satisfied
4 not fully satisfied but generally
3 neither satisfied nor dissatisfied
2 still dissatisfied
1 extremely dissatisfied

Appendix 2: Statistics used
Type: descriptive statistic only.
Measurement level: Correlate: dichotomous, Happiness: metric
Range: depending on the happiness rating scale of the author; range symmetric about zero.

Meaning: the difference of the mean happiness, as measured on the author's rating scale, between the two correlate levels.
OLRCOLRC: Regression coefficient in ordered categorical logistic regression.
Only the sign of the computed coefficient is informative.

Happiness is an ordered categorical variable. Higher categories correspond to being happier.

OLRC < 0 indicates that the odds of being beyond a chosen happiness category-to- be-ing at or below that category decreases when

1) the corresponding metric correlate increases
2) the corresponding category of a categorical correlate is compared to the reference category.

OLRC > 0 indicates an increase in the odds for both the above cases.
