Correlation matrix is not positive definite

[xiangboyulan]

Hi Sacha, Data=read.table("IGD+.txt",header=T)

Network <- estimateNetwork(Data,default = "EBICglasso", corMethod="spearman") Estimating Network. Using package::function:

• qgraph::EBICglasso for EBIC model selection
  • using glasso::glasso Error in bootnet_correlate(data = data, corMethod = corMethod, corArgs = corArgs, : Correlation matrix is not positive definite.

Could you give me some advise? Thanks a lot!

Is the Data object a raw dataset? Can you show what the first 10 lines look like?
