  • Difference between spautoreg and spreg for SAC, SAR and SEM

    Hello,

    I used the SAC command spautoreg and spreg for the same data, and I hope so, for the same distance matrix. However, the spautoreg delivers non-significant measures for RHO and Lambda, the spreg, in contrast, Show significant estimates for Lambda (rho in the drukker Notation). The regression coefficients are also slightly different. Does anyone know, why I got different results (there were also different for SAR and SEM)?

    my notations:

    spautoreg: spautoreg DV IVs, wmfile(matrix) mfc(lin) model(sac)
    spreg: spreg ml DV IVs, id(id) dlmat(matrix) elmat(matrix)

Working...
