“…The basic idea is to derive the best linear unbiased predictor (BLUP) suggested by Goldberger (1962) for the linear regression model but applied to the random-effects panel data model. This BLUP has been extended to handle serial correlation in the remainder error (Baltagi and Li, 1992), spatial correlation (Baltagi and Li, 2004;Baltagi et al, 2012), both spatial and serial correlation (Song and Jung, 2002) and the two-way error components model (Kouassi et al, 2011), to mention a few. Applications include Schmalensee et al (1998), Baltagi et al (2000), Hoogstrate et al (2000), Frees and Miller (2004), Rapach and Wohar (2004) and Brucker and Siliverstovs (2006); see Baltagi (2008) for a recent survey.…”
