module Distribution
# From Wikipedia:
# In probability theory and statistics, the exponential distribution
# (a.k.a. negative exponential distribution) is a family of continuous
# probability distributions. It describes the time between events in a
# Poisson process, i.e. a process in which events occur continuously
# and independently at a constant average rate.
#
# Parameter +l+ is the rate parameter, the number of occurrences/unit time.

##
# :singleton-method: rng(l)
# Returns a lambda, which generates exponential variates
# with +l+ as rate parameter
##
# :singleton-method: pdf(x,l)
# PDF of exponential distribution, with parameters +x+ and +l+.
# +l+ is rate parameter
##
# :singleton-method: cdf(x,l)
# CDF of exponential distribution, with parameters +x+ and +l+.
# +l+ is rate parameter
##
# :singleton-method: p_value(pr,l)
# Inverse CDF of exponential distribution, with parameters +pr+ and +l+.
# +l+ is rate parameter
