- | When the expected variance is very small or the covariance matrix is close to non-positive definite, try with two different starting values (e.g., much smaller = 0.00001 and much bigger = 1000 when the expected variance is between 0 and 10). | + | When the expected variance is very small or the covariance matrix is close to non-positive definite, try with two different starting values (e.g., much smaller = 0.00001 and much bigger = 1000 when the expected variance is between 0 and 1). |
The REMLF90 program will always estimate a positive variance (within the parameter space) even if there is no variance (using wrong data or format and/or a completely wrong model). | The REMLF90 program will always estimate a positive variance (within the parameter space) even if there is no variance (using wrong data or format and/or a completely wrong model). | ||
If AIREMLF90 does not converge but REMLF90 converges with the same data set and the same model, rerun REMLF90 with a small starting value to check the estimate because it could be artifact. | If AIREMLF90 does not converge but REMLF90 converges with the same data set and the same model, rerun REMLF90 with a small starting value to check the estimate because it could be artifact. |
