NAME
PDL::GSL::CDF - PDL interface to GSL Cumulative Distribution Functions

DESCRIPTION
This is an interface to the Cumulative Distribution Function package present in the GNU Scientific Library.

Let us have a continuous random number distributions are defined by a probability density function p(x).

The cumulative distribution function for the lower tail P(x) is defined by the integral of p(x), and gives the probability of a variate taking a value less than "x". These functions are named cdf_NNNNNNN_P().

The cumulative distribution function for the upper tail Q(x) is defined by the integral of p(x), and gives the probability of a variate taking a value greater than "x". These functions are named cdf_NNNNNNN_Q().

The upper and lower cumulative distribution functions are related by "P(x) + Q(x) = 1" and satisfy "0 <= P(x) <= 1" and "0 <= Q(x) <= 1".

The inverse cumulative distributions, "x = Pinv(P)" and "x = Qinv(Q)" give the values of "x" which correspond to a specific value of "P" or "Q". They can be used to find confidence limits from probability values. These functions are named cdf_NNNNNNN_Pinv() and cdf_NNNNNNN_Qinv().

For discrete distributions the probability of sampling the integer value "k" is given by p(k), where "sum_k p(k) = 1". The cumulative distribution for the lower tail P(k) of a discrete distribution is defined as, where the sum is over the allowed range of the distribution less than or equal to "k".

The cumulative distribution for the upper tail of a discrete distribution Q(k) is defined as giving the sum of probabilities for all values greater than "k". These two definitions satisfy the identity "P(k) + Q(k) = 1".

If the range of the distribution is 1 to "n" inclusive then "P(n) = 1", "Q(n) = 0" while "P(1) = p(1)", "Q(1) = 1 - p(1)".
