::mfp::math::stat_stoch::avg(0...) :

Function avg(...) returns average value of an arbitary number of parameters.

::mfp::math::stat_stoch::beta(2) :

Function beta(z1, z2) returns beta function value of complexes z1 and z2, note that real part of z1 and z2 must be positive.

::mfp::math::stat_stoch::gamma(1) :

Function gamma(z) returns gamma function value of complex z, note that real part of z must be positive.

::mfp::math::stat_stoch::gavg(0...) :

Function gavg(...) returns geometric mean value of an arbitary number of parameters.

::mfp::math::stat_stoch::havg(0...) :

Function havg(...) returns harmonic mean value of an arbitary number of parameters.

::mfp::math::stat_stoch::max(0...) :

Function max(...) returns maximum value of an arbitary number of parameters.

::mfp::math::stat_stoch::med(0...) :

Function med(...) returns medium value of an arbitary number of parameters. If the number of parameters is even, returns average of the middle two parameters.

Function min(...) returns minimum value of an arbitary number of parameters.

::mfp::math::stat_stoch::ncr(2) :

Function nCr(x, y) calculates the number of y-combination of a set S which has x elements. Note that x, y are non-negative integer, x >= y.

::mfp::math::stat_stoch::npr(2) :

Function nPr(x, y) calculates the number of y-permutation of a set S which has x elements. Note that x, y are non-negative integer, x >= y.

::mfp::math::stat_stoch::rand(0) :

rand() function returns a random float number between 0 (inclusive) and 1 (exclusive).

::mfp::math::stat_stoch::stdev(0...) :

Function stdev(...) returns standard deviation of an arbitary number of parameters.

Note that the parameters are a sample of a larger set.

::mfp::math::stat_stoch::stdevp(0...) :

Function stdevp(...) returns standard deviation of an arbitary number of parameters.
