I've been struggling with a problem since a while, hopefully someone here could help me out.

The problem:

I want to use the coefficients from a previous research to make a prediction equation. The problem is that the paper only lists the standardized (beta) coefficients of the independent variables, the F-statistic and their p-value.

I don't have the unstandardized coefficients neither the intercept of the equation.

I think it is necessary to convert unstandardized the coefficients to standardized coefficients.

How do I calculate the intercept?

Is this possible? Is there any formula to convert it?

I would greatly appreciate any help.

Thanks
