Checks whether the assessments in a HARSAT assessment object have converged. Currently only does detailed checks for models with normal or lognormal errors (all chemical timeseries and some biological effects). Here it checks whether:
fixed effect estimates are away from their bounds
random effect estimates are lower than their upper bounds; they can of course be equal to zero
standard errors are present for model predictions and fixed effects estimates
standard errors of the fixed effects estimates are realistic (very small standard errors indicate problems with the numerical differencing used to compute the standard errors)
