    • The Scan-LM to Test Instability in the Constant Coefficient of Spatial Autoregressive Models 

      López Hernández, Fernando A.; Mínguez Salidos, Román (Pontificia Universidad Católica del PerúPE, 2021-05-06)
      This paper presents a test based on the principle of Lagrange Multipliers to identify spatial instability in the constant coefficient of regression models including substantive spatial dependence. The test has been adapted ...

    • A Simple Test of Spatial Autocorrelation for Centered Variables 

      Mur, Jesús (Pontificia Universidad Católica del PerúPE, 2021-05-06)
      We present a simple test of spatial autocorrelation based on the skedastic structure of the spatial series. Its distribution function is known for all sample sizes. Moreover, it is very simple to obtain, specially in a ...
