Hi Jennifer.<br><br>Your output includes one other concerning error that
appears just after phase 1 ends. Can you say something about the model
you are fitting? Which effects have you included?<br clear="all"><br>Nathan Doogan<br>

After letting my RSiena model for 12 hours on a high memory machine I received the following output. What advice can you provide to help me overcome this error?<br>
