Initial_estimation_checks:: The forecast error variance in the multivariate Kalman filter became singular

Hello everyone,

Recently I was trying to run a model with Bayesian estimates, and what happens is that I get this error, what is the recommended thing to do in these cases?
I ran the model with the parameters I calibrated and the model ran smoothly, but here you recommend that I re-calibrate the parameters, will this be the best option?
Thanks in advance.
