Mean value,
, of this density is given by a geometric combination of rvc and given fixed point,
.
is the coefficient of the geometric combimation
Standard deviation of the random walk is proportional to one
-th the mean. This is achieved by setting
and
.
The standard deviation of the walk is then:
.
