In the second example, the parameter vector β had k elements, as did the vector of regressors x, yielding k moment conditions. Ignoring peculiar cases, we see that a model of m equations in m unknowns has a unique solution; and because the residual equations in these examples were linear...

We explore the issue of estimating a simple agent-based model of price formation in an asset market using the approach of Alfarano et al. (2008) as an example. Since we are able to derive various moment conditions for this model, we can apply generalized method of moments (GMM) estimation...
We found that both GQL and GMM approaches are less likely to result in non-convergence as opposed to the LAP approach. A simulation study was conducted and a numerical example was presented for illustrative purposes.Wang, BeiArizona State UnivWilson, Jeffrey R....
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. ...

Let's take a simple example. Assume we have 100 data points and need to cluster them into two groups. We can write r_ic(i=20,c=1) as follows. Where i represents the data point's index, and c represents the index of the cluster we are considering. Please note at the beginning, ...
