### GetDist : parameter statistics table

Posted:

**September 24 2024**With getdist-gui, in the sample likelihood constraints panel, I got a very strange upper and lower bound.

The lower bound value is bigger than best fit value, while the upper bound value is a abnormal small value.

It is nothing to do with the model.

The chains are converged with |R-1|<0.01. The contour and marginalized constraints stats are quite normal. see red box below.

Bestfit values are also quite normal.

No idea why the boundary values are strange. see yellow box below.
