These functions provide information about the two-sided power distribution
with location parameter equal to `m`

and shape equal to
`s`

: density, cumulative distribution, quantiles, and
random generation.

The two-sided power distribution has density

*
f(y) = s(y/m)^(s-1), y<=m*

*
f(y) = s((1-y)/(1-m))^(s-1), y>=m*

where *m* is the location parameter of the distribution and
*s* is the shape, and *0<y<1*.

For *s=1*, this is the uniform distribution and for
*s=2*, it is the triangular distribution.
