THE APPLICATION OF THE SIMPLE METHOD OF ESTIMATING FIXED EFFECTS FOR DATA WITH UNEQUAL REPLICATION;

By using panel data and fixed effects regression models,we have developed in this paper a new method which can be used to correct the omitted variable bias in some regression models.

A Study on a Class of Dynamic Spatial Fixed Effect Models

Diagnostic checking for dynamic panel models with fixed effects when both n and T are large

The height growth curve and mean height growth curve under different densities were drawn according to calculated value and fixed effect value,which showed the advantages of the mixed model,i.

This paper deals with the extention of traditional wheel/rail interactions to wheel/roller case and investigating the gravitational effects under contact conditions with different wheel and rail(or roller)profiles.

In this paper, we calculated the gravity effect of water-impoundment in the front area of the Three Gorges reservoir on several different water levels with a high precise numerical simulation and compared the gravity anomaly obtained by numerical simulation with that by measured in a local gravity monitoring net during the first water-impoundment in the Three Gorges.

In this paper,the gravity effects caused by the changes of seometric and physical parametere of a fault are discussed when the tectonic stresses applied to the fault without any models siven.
