MIRR Program for 17bii+ - Walter - 01-26-2005 Is any one got a program for calculating Modified Internal Rate of Return (MIRR) with 17bii+?
Re: MIRR Program for 17bii+ - Bob Wang - 01-26-2005 How about this? http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv014.cgi?read=62730

Re: MIRR Program for 17bii+ - Frank - 01-26-2005 Bob, I believe you once made a reference of the Black-Sholes computation for the HP 200lx. Is it possible for you to refer me to it or to send me as an e-mail. Thanks for your help.

Black-Scholes on the 200lx - Bob Wang - 01-26-2005 Frank: The shortest, most accurate implementation of Black-Scholes not using UTPN is courtesy of Tizedes Czaba's suggestion of using a Taylor series. However, it is also the SLOWEST, taking well over a minute on my 17Bs and 19Bs. I would appreciate it if you would try it on your 200lx, and time the execution. IF the speed is acceptable, I would recommend using that instead of the different polynomial methods I have posted on my shabby home page. Bob
Taylor Series Approximation: Re: Black-Scholes on the 200lx - Bob Wang - 01-26-2005 Frank: In case it's not evident, please replace "SIGMA" with the summation operator.

SIGMA=SIGMA on the 200lx - Bob Wang - 01-26-2005 Frank: Oops, I guess SIGMA *IS* just SIGMA on the 200lx.

Re: SIGMA=SIGMA on the 200lx - Frank - 01-26-2005 Thanks Bob, I'll keep you posted.
Re: MIRR Program for 17bii+ - Walter - 01-28-2005 Thanks!! Bob! I will try it!!
