Appendix 2: Statistics used

Symbol | Explanation |

b-fix | REGRESSION COEFICIENT in fixed effects analysis Type: test statistic WDH symbol: b-fix Primary correlate level: metric Secondary correlate level: nonmetric Happiness level: metric Theoretical range: unlimited Meaning: Variant of usual (non-standardized) regression coefficient (b), which controls for the secondary variables, by focusing on differences from a fixed level, such as the mean in a category. Aims to reduce the residual variance and to improve the precision of the regression coefficient.

Beta | STANDARDIZED REGRESSION COEFFICIENT by LEAST SQUARES (OLS) Type: test statistic. Measurement level: Correlates: all metric, Happiness: metric. Range: [-1 ; +1] Meaning: beta > 0 « a higher correlate level corresponds to a higher happiness rating on average. beta < 0 « a higher correlate level corresponds to a higher happiness rating on average. beta = 0 « no correlation. beta = + 1 or -1 « perfect correlation. |
