The ordinary equation of linear regression has the form:

    y=B+b1x1+b2x2+e

Where 

    B is intercept
    b1,b2-beta-coef
    x1,x2-real values of obs

I want write the equation for a Cox regression. I get the follow result table

    	    Beta	     t-value	   Wald	    p
    AGE 	0,105520	3,373554	11,38087 0,000743
    ANTIGEN	0,583551	1,366189	1,86647	 0,171889

How do I use these beta coefficients to write the equation for Cox regression?
