- statistics: [m, v] = nbinstat (n, p)
Compute mean and variance of the negative binomial distribution.
Arguments
-
n is the first parameter of the negative binomial distribution. The
elements of n must be natural numbers
-
p is the second parameter of the negative binomial distribution. The
elements of p must be probabilities
n and p must be of common size or one of them must be scalar
Return values
-
m is the mean of the negative binomial distribution
-
v is the variance of the negative binomial distribution
Examples
| n = 1:4;
p = 0.2:0.2:0.8;
[m, v] = nbinstat (n, p)
[m, v] = nbinstat (n, 0.5)
