For the flight-by-flight sequential importance sampling routine of the
crackR package, the default is to output SFPOF at the start and end of
a number of subintervals of flights. Also output in the results
object is the probability
of failure of each interval: `pof.int`

. This function calculates
and "average" value of
SFPOF for each flight in each subinterval using `pof.int`

,
yielding SFPOF results in the familiar format for plotting.

calcSfpofFromPofInt(pof.int)

`pof.int` |
data.frame of the subintervals of a crackR run with columns indicating the number of flights in each interval and the failure probability of each interval. pof.int is standard output in a crackR run. |

Like the interval version of the routine, SFPOF will converge more quickly for many problems when averaging estimates over a number of flights. Using this function to process flight-by-flight results will be approximate within each subinterval, but these will be less approximate in general than those obtained by the interval routine.
