Computes the probability mass function of a mixture of the negative binomials.
1 | dmixnegbinom(x, pis, size, probs)
|
x |
A scalar or vector of non-negative integer values. |
pis |
A vector collecting the mixture weights. See details. |
size |
A postive value corresponding to the target for number of successful trials. |
probs |
A vector collecting the probabilities of success for each mixture component. |
The argument pis
is a vector with length equal the number of components in the mixture. The vector pis
must sum up to one, e.g. c(0.7, 0.2, 0.1)
.
All the negative binomials contributing to the mixture are assumed to have the same size
.
Value of the probability mass function of the mixture of negative binomials evaluated at x
