<p class="MsoNormal">I installed Arni’s new IDE and that now creates a std file. However, when I try to run MCMC I get an error “Error in matrix inverse -- matrix singular in inv(dmatrix)”. Since it was able to create the std report, why does the calculations
for the MCMC create an error? Anyone else come across this issue and found a solution?<o:p></o:p></p>
