GSLIB Help Page: POSTSIM
Description:
-
postsim allows a number of summaries to be extracted from a set
of simulated realizations:
-
the ``E-type'' estimates, i.e., the point-by-point 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
p-quantile
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 E-type estimate, the
fraction and mean above threshold, the fraction and mean below
threshold, or the conditional p-quantile
values.
-
iout and outpar:
iout=1 computes the E-type estimate,
iout=2 computes the probability and mean above and below the
value outpar, iout=3 computes the z-value
(p-quantile) 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
