Even when there is no variance, remlf90 will estimate a positive variance (within the parameter space), which will be determined by the starting value. If you are not sure if there is any variance, use a small starting value such as 0.1 or 0.01. If the estimate does not change, probably there is no variance, so check your parameter file, model, and/or data again. If airemlf90 does not converge but remlf90 converges with the same data set and the same model, rerun remlf90 with a small starting value because the estimate could be artifact. | Even when there is no variance, remlf90 will estimate a positive variance (within the parameter space), which will be determined by the starting value.
