A recent mathematical model by Horvath which predicts the process of participation in group discussions is compared to several alternative models. The models can be applied to data for which the basic unit is the act and to data for which the basic unit is a continuous sequence of acts. In both...

Based on large-sample stochastic approximations, we obtain asymptotic bias and mean squared error for the k-class estimators of an identified but misspecified equation with an arbitrary number of endogenous variables in linear simultaneous-equations model. The specification error considered here...
