“…Operations research are also applied, e.g., statistical analysis, discriminant analysis (Haslem et al, 1992), logit and probit regression models (Canbas et al, 2005), artificial neural network models such as fuzzy clustering and self-organizing neural networks (Alam et al, 2000), the back-propagation neural networks model (Tam, 1991), multiple criteria decision-making (Pasiouras et al, 2010;Niemira and models of economic and financial instability and of behavioral finance (Minsky, 2008). Liow and Webb (2009) investigate common factors in the securitized real estate markets of the Untied States, United Kingdom, Hong Kong and Singapore. The results, although preliminary, are indicative suggesting more studies to explore how common factors in joint with a local market portfolio could help in explaining the return-generating process of securitized real estate (Liow and Webb, 2009).…”
