Instead of Failed to parse (Missing <code>texvc</code> executable. Please see math/README to configure.): l_x or even Failed to parse (Missing <code>texvc</code> executable. Please see math/README to configure.): L_x=\frac{l_x+l_{x+1}}{2} (when linear approximation hold), the survival function is(was) often given by Failed to parse (Missing <code>texvc</code> executable. Please see math/README to configure.): Z_x=\frac{L_{x+1}}{L_x} i.e the probability for somebody which age relies between x and x+1 at time t, to survive one year (to be alive at time t+1, and aged between x+1 and x+2).--Nicolas Brouard 18:15, 5 September 2012 (CEST)
