Previous research presented in numbers of studies strongly suggests that locating a cluster generates valuable benefits to clustered firms. These include better access suppliers and other scarce inputs, superior knowledge innovation, position from which build social network as well proximate successful competitors. Yet when the positive impact agglomeration clustering has been questioned on str...

We present a polynomial-time algorithm for c-planarity testing of clustered graphs with fixed plane embedding and such that every cluster induces a subgraph with at most two connected components.

In various applications with large spatial regions, the relationship between response variable and covariates is expected to exhibit complex patterns. We propose a spatially clustered varying coefficient model, where regression coefficients are allowed vary smoothly within each cluster but change abruptly across boundaries of adjacent clusters, we develop unified approach for simultaneous estim...
