Changes from the versions of programs printed in Morris and Doak:

In the programs VitalSim.m and DemoMetaSim.m, the calls for loading 
and saving variable files, using input strings for file names, used incorrect
syntax. Lines 75 and 95 in VitalSim.m and lines 54 and 74 in DemoMetaSim.m
have been changed to correct this problem. 

The program StochSens.m in Box 9.4 had an error in the calculation of the sensitivity and 
elasticity values for variances and covariances. This was corrected on 10/28/02.

logregA.m in Box 11.2 had an error on line 15: a semicolon, not a colon, is needed between the 
two terms in the square brackets. This was corrected in February 2004. 

A change in the use of SUBS in the Symbolic Logic Toolbox means that we
 changed the code of both Vitalsens.m and Limitsens.m (Boxes 9.1 and 9.2, respectively)
 
 In MultiSiteCount, we've changed the calculation of the deterministic mean matrix to 
 reflect the true mean of the lognormally-distributed vital rates that are population-
 specific lambda values; the means of these lognormally-distributed values should be
 the mean + 0.5variance of the normally distributed log-lambda values (see equation 8.8 in
 Chapter 8 of Morris and Doak). This change appears on line 42 of the program. It effects 
 the estimate of the metapopulation's deterministic lambda value, but not any other output 
 of the program.
