The covariance is significant, so I conclude there is an underlying correlation between the two random intercepts. Now, before you rush out and try this, there are a few caveats. Behind the scenes, Stata is doing a lot of work for you. Every random effect has to be numerically ...

This VCE accounts for the within-group correlation of the errors, and it is given by Vˆcluster=N−1N−kgg−1(∑i=1Nx′ixi)−1Mc(∑i=1Nx′ixi)−1 where Mc=∑j=1gX′j(eˆjeˆ′j)Xj Xj is the nj×k matrix of observations on xi in group j, eˆj is the nj...
In presence of cross or time correlation beyond the factor structure, the estimate for beta is biased (but still consistent): see Theorem 3 in Bai 2009, which derives the correction term in special cases. However,regifedoes not implement any correction. You may want to add enough factors unt...
