The paper deals with the mathematical modelling of some requirements that must be fulfilled at a choice of entrepreneurial intentions. The author mathematically formulates some special constraints and various types of the objective function in linear optimization models of entrepreneurial...

Studying behaviour in economics, sociology, and statistics often involves fitting models in which the response variable depends on a dummy variable (also known as a regime switch variable) or in which the response variable is observed only if a particular selection condition is met. In either...

Macroeconometric and financial researchers often use secondary or constructed binary random variables that differ in terms of their statistical properties from the primary random variables used in micro-econometric studies. One important difference between primary and secondary binary variables...

This paper includes a simulation study on the bias and MSE properties of a two-step probit model estimator for handling missing values in covariates by conditional imputation. In one smaller simulation it is compared with an asymptotically efficient estimator and in one larger it is compared...

Die Messungen von dichotomen Individualeigenschaften können fehlerbehaftet sein. Diese Messfehler sind in der Regel nicht erkennbar und können somit nicht korrigiert werden. Damit besteht die Möglichkeit, dass Messfehler der Individualebene Aggregate wie Häufigkeiten und Anteilswerte...

To match the NBER business cycle features it is necessary to employ Generalised dynamic categorical (GDC) models that impose certain phase restrictions and permit multiple indexes. Theory suggests additional shape restrictions in the form of monotonicity and boundedness of certain transition...
