The simulation results showed that the imbalance of data due to missing observations led to lower precision and lower exactness of variance component estimation,to underestimation of the error of fixed effects as well as to higher type Ⅰ error rate for fixed effect test.

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.

Testing enhances memory, which exposits "testing effect" incisively.

The writer finds that the testing effects of test-based study are superior to those of review.

Based on the panel data of per human capital and growth rate of per GDP between 1997-2006,the paper makes an in-depth analysis of the data using the index of Gini coefficient per human capital and the panel data fixed effect model.

Our empirical study result shows that: ① random effect model and fixed effect model are better than pooled regression model; ② the stock market and size effect don’t affect the closed-end fund discount; ③ change of closed-end fund discount exhibits the seasonal effect and reverts to the mean level of the industry, fund manager and fund performance .
