“…Van der Tas (1988) introduced indices to measure the extent of comparability (harmony) in the financial statements of companies and since then there has been significant improvements in methods, including criticism of existing indices and development of new indices (Cooke, 1989;Tay & Parker, 1990;Herrman & Thomas 1995;Archer, Delvaille, & McLeay, 1995;Lainez et al 1996, Archer, Delvaille, & McLeay, 1996Krisement, 1997;McLeay, et al 1999, Canibano & Mora 2000Aisbitt, 2001). This study uses the flexible framework of indices called the T index (Taplin, 2004;Astami et al, 2006) which has been extended to incorporate statistical inference techniques to allow testing of hypotheses (Taplin, 2010) and sophisticated practices to deal with previous criticisms of indices (Taplin, 2011).…”
