In this note we derive the rate of divergence of the penalty term for consistent model selection in the linear regression model under a general error structure.

About 10% of primary school students in developing countries have poor vision, but very few of them wear glasses. Almost no research examines the impact of poor vision on school performance, and simple OLS estimates are likely to be biased because studying harder often adversely affect one’s...

On the strength of the theory of agricultural circular economy, the mutual relation between the development of agricultural circular economy and new village construction is analyzed. The results show that developing agricultural circular economy and constructing new village is the mutual...
