MC-REWEIGHT: Copy part of a log file while changing iteration weights. MC-reweight operates much like log-copy except that it also changes the weights for iterations by altering the records of type 'i'. This allows the iterations to be changed so as to produce an importance sampling estimate for some distribution other than the one originally sampled, provided a program for computing the appropriate weights has been written. Usage: mc-reweight logfile-in range logfile-out < file-of-log-weights Records with negative indexes or with indexes in the indicated range are copied from logfile-in to a newly-created logfile-out, except that records of type 'i', which record information on Monte Carlo iterations, are altered by adding values read from standard input to the log weights recorded in these records. The range has the usual [low][:[high]][%modulus] form, as described in parse_range in misc.c. If high and the colon are omitted, high defaults to low. If high is omitted but the colon is present, the range extends to the end of the file. Copyright (c) 1995-2004 by Radford M. Neal
