GSLIB Help Page: POSTSIM

Description:

postsim allows a number of summaries to be extracted from a set
of simulated realizations:

the ``Etype'' estimates, i.e., the pointbypoint average of the
realizations.

Compute the variance of the conditional distribution.

the probability of exceeding a fixed threshold, the average
value above that threshold, and the average value below that threshold.

the value where a fixed conditional cumulative distribution
function (cdf) value p is reached, i.e., the conditional
pquantile
value.

Parameters:

simfl: the output simulation file that contains all of the
realizations. This file should contain the simulated values, one
value per line, cycling fastest on x then y then
z and last per simulation.

nsim specifies the number of realizations.

tmin and tmax: all values strictly less than tmin
and strictly greater than tmax are ignored.

nx, ny, and nz specify the number of nodes in the
x,y, and z direction.

outfl: an output file that contains the Etype estimate, the
fraction and mean above threshold, the fraction and mean below
threshold, or the conditional pquantile
values.

iout and outpar:
iout=1 computes the Etype estimate,
iout=2 computes the probability and mean above and below the
value outpar, iout=3 computes the zvalue
(pquantile) corresponding to the cdf value
outpar=p, iout=4 computes
the symmetric probability interval (total width = outpar),
and iout=5 computes an estimate of the conditional variance
