(29 years difference); C-BW-c-sq-n-11-a OPRC = +.20 ns OPRC controlled for:
-gender C-BW-c-sq-n-11-a OPRC = -.03 ns OPRC additionally controlled for:
-schooling
-social background. C-BW-c-sq-n-11-a OPRC = -.09 ns OPRC additionally controlled for:
-family status,
-labour market status
-self perceived health
-wealth.

OPRC (Ordered Probit Regression Coefficient) cannot be interpreted as an absolute effect-size. The coefficients only denote relative differences in (not-significant) correlation between mathematical ability and future happiness.
