In multiple regression, if I wanted to determine the effect on the dependent variable of a one unit increase in one independent variable, not if all other independent variables are held constant but for basically the value of the dependent variable after I fill out the regression equation with all of the estimated coefficients, how do I go about it? For example, if I wanted the effect of a one percent increase in x1 on the earnings of a 30 year old male (and x2 is age and x3 is male/female) (and y is earnings)? I'm asking just in general.
Homework Answers
Multiple regression equation will be given as
where 
Where y is earning =Dependent variable
The change in the dependent variable should be interpreted as percentage point.
Here I have increased one percentage in x1 variable
Predicted percentage change in earnings will depend upon the
regression coefficient 
If
there will be 0.3% increase in earnings
If
there will be 0.5% increase in earnings
If
there will be 1 % increase in earnings
