calculate an interest on par with a term structure
ParRate(termstructure, n, step, starttime, frequency)
ParRate(termstructure, paymenttimes, frequency)
ParRate(termstructure, schedule, frequency)
yield term structure; term structure
positive integer; number of payments
positive; length of the interval between payments in years
Annual, Bimonthly, EveryFourthMonth, Monthly, Quarterly, or Semiannual; payment frequency
list or Vector; payment times
non-negative constant; start of payments
schedule data structure; payment schedule
The ParRate command calculates the implied par rate for a given sequence of payments at the given times.
The ParRate(termstructure, n, step, starttime, frequency) calling sequence calculates the interest rate that is equivalent to n payments every step years starting at starttime based on the given yield term structure. The optional frequency parameter can be used to specify the compounding frequency for the returned rate. By default, Annual frequency is used.
The ParRate(termstructure, paymenttimes, frequency) calling sequence is similar to the above except that in this case irregular payment times can be given.
The ParRate(termstructure, schedule, frequency) calling sequence will calculate the par rate for interest payments that occur according to the given schedule.
