ABSTRACT
As noted above we present the results pertaining to centering in the context of examples. More formal presentation of these results can be found in Kreft, de Leeuw, and Aiken (1995) and Snijders and Berkhof (2008). Other expositions on centering can be found in Enders and Tofighi (2007); Hox (2002); Misangi, LePine, Algina, and Goeddeke (2006); Raudenbush and Bryk (2002); and Snijders and Bosker (1999).
