Specifies a uniform prior distribution on a real-valued scalar parameter.
UniformPrior(lo = 0, hi = 1, initial.value = NULL)The lower limit of support.
The upper limit of support.
The initial value of the parameter in question to
use in the MCMC algorithm. If NULL then the mean (lo +
hi)/2 is used.
