I am using the maxbfgs function in the maxLik package for the maximum likelihood function i created, but keeps getting the following error: Error in chol.default(mInvSigma) : the leading minor of order 1 is not positive definite Any suggestions would be very appreciated.
Try following the posting guide and creating a minimal reproducible example. Also, perhaps contact the maintainer of the maxLik package with your reproducible example.
Yes, you could do it (with a minimal reproducible example) through the "help" forum at maxLik's R-Forge site: https://r-forge.r-project.org/projects/maxlik/ Best regards, Arne
