Tīmeklis2013. gada 3. jūl. · See what happens when we throw a nonsense probability at the C++ and native R functions for sampling from binomial distributions, certainly the R returning NA and a warning is preferential (at least to us) than the result from the C++ function. Remember however that C++ has no way of natively coding NA for integer types. grant thornton healthcare consulting https://corcovery.com

Tīmeklis2007. gada 24. nov. · I guess the problem is that in the numerator you have "0.023*z [i]" but "0.023+z [i]" in the denominator. Thus, some p [i] can be outside of [0,1] which would produce NAs in T. But why a for loop? This code is readily vectorised: p <- exp (-0.834+0.002*x+0.023*z)/ (1+exp (-0.834+0.002*x+0.023*z)) HTH. grant thornton hcm
