In this calculation, subjective well-being correlates most strongly with health (.7), wealth (.6), and access to basic education (.6). [2] [3] This is an example of directly measuring happiness—asking people how happy they are—as an alternative to traditional measures of policy success such as GDP or GNP. Some studies suggest that happiness ...
Yet, Stevenson and Wolfers (2008) show that the survey questions evolved over time, complicating the assessment of changes in happiness. When the data is segmented into consistent sub-periods, a positive correlation between GDP and happiness growth emerges, indicating that the perceived paradox results from mismeasurement of happiness.
In statistics, Goodman and Kruskal's gamma is a measure of rank correlation, i.e., the similarity of the orderings of the data when ranked by each of the quantities. It measures the strength of association of the cross tabulated data when both variables are measured at the ordinal level. It makes no adjustment for either table size or ties.
The economics of happiness or happiness economics is the theoretical, qualitative and quantitative study of happiness and quality of life, including positive and negative affects, well-being, [1] life satisfaction and related concepts – typically tying economics more closely than usual with other social sciences, like sociology and psychology, as well as physical health.
Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.
The coefficient provides "a convenient measure of [the Pearson product-moment] correlation when graduated measurements have been reduced to two categories." [6] The tetrachoric correlation coefficient should not be confused with the Pearson correlation coefficient computed by assigning, say, values 0.0 and 1.0 to represent the two levels of ...

The coefficient of multiple correlation is known as the square root of the coefficient of determination, but under the particular assumptions that an intercept is included and that the best possible linear predictors are used, whereas the coefficient of determination is defined for more general cases, including those of nonlinear prediction and those in which the predicted values have not been ...
