Test of Difference

[adarshad]

Sir
I have run a regression, where I estimated effect of two independent variables A and B on an outcome variable C. How can I compare the regression coefficients of A and B to estimate whether the effect of A is greater or whether B has a stronger impact on C and whether both coefficients obtained are significantly different from each other so that I can assume that both independent variables have differing impacts on the outcome variable.

Can you Help in this regard?

Test whether coef_A - coef_b =0 using a Wald test.
