Rbinom size

TīmeklisThe binomial distribution with size = n and prob = p has density p (x) = choose (n, x) p^x (1-p)^ (n-x) for x = 0, …, n . Note that binomial coefficients can be computed by choose in R . If an element of x is not integer, the result of dbinom is zero, with a warning. p (x) is computed using Loader's algorithm, see the reference below.

Tīmeklis2024. gada 11. apr. · To put this concretely, I simulated the data below, where x1 and x2 are correlated (r=0.8), and where Y (the outcome) depends only on x1. A conventional GLM with all the features included correctly identifies x1 as the culprit factor and correctly yields an OR of ~1 for x2. However, examination of the importance scores … TīmeklisHere’s where the second input parameter - size - of the rbinom() function comes into play. So far, we’ve always left it equal to 1 in all our command lines above, but we can set it to any positive integer: rbinom (1, 20, 0.5) ## [1] 10. The above code is equivalent to taking 20 Bernoulli trials, and then adding their outcomes up. The ...
