 maximum likelihood estimations
 The empirical section employsprobit, multinomial logit, and orderedprobit maximum likelihood estimations toconfirm the stated hypotheses. Two separate maximum likelihood estimations of univariate marginal distributions are performed first, then followed by a maximization of the bivariate likelihood as a function of the dependence parameters. A nonlinear model generating a self-exciting point process is formulated and identification of the model using maximum likelihood estimations is discussed.
