| 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.
