It relies on options on Short Term Interest Rate futures or options on government bond futures. It models the futures price as a mixture of lognormal densities. It also provides with the RNDs and cumulative densities of the money market rate or the government bond yield inferred from the futures price, using the RND of the futures price. It eventually provides with the probability attached to each bond in the delivery basket of a government bond futures to be the cheapest at maturity, using the RND of the bond futures price. The package leverages on the works of Melick, W. R. and Thomas, C. P. (1997) <doi:10.2307/2331318> and B. Bahra (1998) <doi:10.2139/ssrn.77429>.https://github.com/r-universe/williamarrata/actions/runs/27509709482Sun, 14 Jun 2026 18:48:19 GMTyrnd0.1.4successhttps://williamarrata.r-universe.devhttps://github.com/cran/yrndyrnd_functions.Rmdyrnd_functions.htmlyrnd_functions2026-02-18 19:20:022026-06-14 18:48:19
