by short: I'm trying to do a GMM Estimation by using the "pgmm" package in R. Reason for that is to research the impact of Corruption on Public debt. When I'm trying to regress the whole thing, I get"system is computationally singular"as an error. The Variables: d...

The system GMM estimator developed by Blundell and Bond (1998) for dynamic panel data models has been widely used in empirical work; however, it does not perform well with weak instruments. This paper proposes a variation on the system GMM estimator, based on a simple transformation of the ...

Based on the industrial enterprise in Huizhou during 2011-2014 as sample,and through the system GMM estimation for empirical research,it is found that government subsidy motivates a company's RD input in the initial stage,however,when the amount of subsidy exceeds the optimal mean value,the ...
Reduction in expression of GmNAC29 through the interaction of GmWRKY27 and GmMYB174 for stress tolerance in soybean plants has also been investigated by Wang et al. (2015). Dynamic modulation of bHLH and C2H2 TF family in Heena and Kiran variety also strengthens the contrasting phenotype of ...
