Function File: [m, v] = binostat (n, p)

Compute mean and variance of the binomial distribution.

Arguments

  • n is the first parameter of the binomial distribution. The elements of n must be natural numbers
  • p is the second parameter of the 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 binomial distribution
  • v is the variance of the binomial distribution

Examples

n = 1:6;
p = 0:0.2:1;
[m, v] = binostat (n, p)



[m, v] = binostat (n, 0.5)
