Initially I was using mode_compute 6, but that was not identifiying the mode properly (checked through mode plots) and MCMC were not converging. So I started using mode_compute 9.
But now I am getting, warnings:
- Initial sigma much smaller than the given bounded interval.
- Non-finite fitness range
And then finally execution stops with the error:
error using chol
MAtrix must be positive definite
Any suggestions in which direction I should proceed to resolve this?
