Salomon Minkin, Assessing the Quadratic Approximation to the Log Likelihood Function in Nonnormal Linear Models, Biometrika, Vol. 70, No. 2 (Aug., 1983), pp. 367-372 ...

We study in detail the log-linear return approximation introduced by Campbell and Shiller (1988a). First, we derive an upper bound for the mean approximation error, given stationarity of the log ...
