POSTGIBBSF90 Written by Shogo Tsuruta, University of Georgia. 3/20/2001 POSTGIBBSF90 is a post Gibbs analysis program for programs GIBBSF90, GIBBS1F90, GIBBS2F90, GIBBS3F90 and THRGIBBS1F90. It calculates posterior means, median, mode, standard deviations, HPD, effective sample size and auto-correlations. It can also display or print the shape of one or more variance components or a histogram of one component. POSTGIBBSF90 has been tested under Linux using the ABSOFT compiler but will compile under other systems with the SYSTEM() function. To display graphs, a graphical package GNUPLOT needs to be installed.
