Re: [Quantlib-users] SABR global versus local fit

[terry l. <tl...@me...>]

Peter,
Submitted the Rquantlib mod with saber and markofunctional interface to
Dirk. Lined up well with market surface I had (+/- 10% but very close
ATM).There¹s a Shiny app included to make it easier to analyze a large
number of points on the surface (cube is 1384 quotes).

Naive question on normal rates in markovfunctional: for SABR you get
normal vols by setting beta=0, and when I look at the code there is a fit
that refers to SABR and beta, is there a simple place where the model can
be adjusted by fixing a parameter?
