Does anyone know of a reasonable FORMULA with a mathematical basis for
a suggested withdrawal rate in retirement, as a function of

(1) life expectancy
(2) expected real return of investments after taxes
(3) volatility of returns

I see numbers like 4% mentioned as a rule of thumb, but the optimal
withdrawal rate ought to depend on items (1) and (2).
