| + | In both methods, the continued sampling may give you slightly different results from the non-breaking run. | ||
| + | This is because of numerical error. | ||
| + | The saved samples of variance components have limited precision and it creates errors in subsequent sampling. | ||
| + | In general, this error is trivial and you can ignore it. | ||
