Hi, friends,

I'm using "DPdensity" package in R to analyze my data (N=1000). The given
examples in that package ran pretty good. But when I applied it to my data
set, it keeps saying "matrix is not pd in chol subroutine". Is there anyone
has ever used such package can share some ideas? 

Thank you very much,

The package link is given below:
