Geometric Distribution

Distributions associated with the Geometric Equation:

q(1 − q)^k, where q is the probability of success.

dgeom(k, q) Returns the probability density for value k.

pgeom(k, q) Returns the cumulative probability distribution for value k.

qgeom(p, q) Returns the inverse cumulative probability distribution for probability p.

rgeom(m, q) Returns a vector of m random numbers having the geometric distribution.

Arguments:

• k is a scalar or vector of real values greater than 0. To allow integration and other operations over this argument, values outside of the stated range are allowed, but they produce a 0 result.
• q is a real probability between 0 and 1.
• p is a real probability between 0 and 1.
• m is an integer greater than 0.

Notes:

• For definitions of the functions, and information on generating random numbers, see the Density and Distribution definitions.
