unidstat

Discrete uniform mean and variance

Syntax

[M,V] = unidstat(N)


Description

[M,V] = unidstat(N) returns the mean and variance of the discrete uniform distribution with minimum value 1 and maximum value N.

The mean of the discrete uniform distribution with parameter N is (N + 1)/2. The variance is (N² – 1)/12.

Examples

[m,v] = unidstat(1:6)
m =
  1.0000  1.5000  2.0000  2.5000  3.0000  3.5000
v =
  0  0.2500  0.6667  1.2500  2.0000  2.9167
