This paper studies the construction and approximation of neural network operators with a centered bell-shaped Gaussian activation function. Using a univariate Gaussian function a class of Cardaliaguet-Euvrard type network operators is constructed to approximate the continuous function, and the Jackson type theorems of the approximation and some discussions about the convergence are given. Furth...

The origin of this article is a conversation I had with a first-semester calculus student in the fall of 2005. We had just covered the idea of the derivative in class. I had taken the standard approach of motivating the derivative with the velocity and slope interpretations while trying to emphasize that it is a more general concept involving rate of change. One of my students was not satisfied...

This paper presents a method for estimating a class of panel data duration models, under which an unknown transformation of the duration variable is linearly related to the observed explanatory variables and the unobserved heterogeneity ~or frailty! with completely known error distributions+ This class of duration models includes a panel data proportional hazards model with fixed effects+ The p...
