“…Of course, the normal CDF ( ) may be used in place of the logistic function ( ), in which case we have the MGARP model, the last letter standing for "probit". Logit speci…cations can be found in the literature stressing …-nancial applications (e.g., Foresi and Peracchi, 1995;Rydberg and Shephard, 2003;Christo¤ersen and Diebold, 2006;Anatolyev and Gospodinov, 2009), while probit is more favored in macroeconomic applications (e.g., Chauvet and Potter, 2005;Dueker, 2005;Kauppi and Saikkonen, 2008) as well as in microeconomic empirical examples (e.g., Mosconi and Seri, 2006). The assumption of the logistic distribution (4) as well as the dynamic equation (5) are testable; see, for example, a review in Gouriéroux (2000).…”
