Marginal correlation analysis
WebMar 28, 2014 · The denominator is always positive, so the sign of the estimated coefficient depends on the numerator. Then if you have (for example) 0 < C ^ o v ( Y, X 1) < C ^ o v ( X 1, X 2) ⋅ C ^ o v ( Y, X 2) V ^ a r ( X 2) which is perfectly possible, then you will have positive pair-wise correlation between the dependent variable and regressor X 1 ...
