 Close to a solution, we have found that other algorithms
make much more rapid progress than EM; in particularly, we found
that the extrapolated SCD updates usually performed best). For
larger data sets, more updates in the main model fitting and
refinement steps may be needed to obtain a good fit.</p>
<p>For larger data sets, more than 200 updates may be needed to obtain
a good fit.</p>
